通过以上方案可知，本申请提供了一种电源检测方法，应用于电源控制器，包括：获取N相电源中的任一相目标电流在单一开关周期内的采样序列；其中，N≥2；基于采样序列确定目标电流在单一开关周期内的脉动次数；在脉动次数大于N+1的情况下，确定N相电源为TLVR类型的N相电源。It can be seen from the above scheme that the present application provides a power supply detection method, which is applied to a power supply controller, including: obtaining a sampling sequence of the target current of any phase in an N-phase power supply within a single switching cycle; wherein N≥2; determining the number of pulsations of the target current within a single switching cycle based on the sampling sequence; when the number of pulsations is greater than N+1, determining that the N-phase power supply is a TLVR type N-phase power supply.

可见，本申请能够利用电源控制器自动检测N相电源中的任一相目标电流在单一开关周期内的采样序列，然后基于采样序列可以确定该单相目标电流在单一开关周期内的脉动次数，也就确定了该单相目标电流在单一开关周期内的电流跳变次数；在脉动次数大于N+1的情况下，确定N相电源为TLVR类型的N相电源。因为TLVR类型的N相电源的单相电流在单一开关周期内的电流跳变次数最多为2N+1，而VR类型的N相电源的单相电流在单一开关周期内的电流跳变次数最多为N。因此在某一N相电源的单相电流在单一开关周期内的电流跳变次数大于N+1时，其必定不是VR类型的N相电源，而是TLVR类型的N相电源。据此，本申请可自动检测出电源的类型，而无需人工参与，因此可以提升检测效率和准确性，也能够为电源配置提供前提基础。It can be seen that the present application can utilize the power supply controller to automatically detect the sampling sequence of the target current of any phase in the N-phase power supply within a single switching cycle, and then determine the number of pulsations of the single-phase target current within a single switching cycle based on the sampling sequence, and thus determine the number of current jumps of the single-phase target current within a single switching cycle; when the number of pulsations is greater than N+1, determine that the N-phase power supply is a TLVR type N-phase power supply. Because the number of current jumps of the single-phase current of the TLVR type N-phase power supply within a single switching cycle is at most 2N+1, while the number of current jumps of the single-phase current of the VR type N-phase power supply within a single switching cycle is at most N. Therefore, when the number of current jumps of the single-phase current of a certain N-phase power supply within a single switching cycle is greater than N+1, it must not be a VR type N-phase power supply, but a TLVR type N-phase power supply. Accordingly, the present application The type of power supply can be automatically detected without human intervention, thus improving detection efficiency and accuracy, and also providing a prerequisite for power supply configuration.

相应地，本申请提供的一种电源检测装置、设备、非易失性可读存储介质及电路，也同样具有上述技术效果。Correspondingly, a power supply detection device, equipment, non-volatile readable storage medium and circuit provided by the present application also have the above-mentioned technical effects.

在本实施例中，N≥2。电源控制器是N相电源所连主板中的控制器，其用户控制电源的运行逻辑。In this embodiment, N≥2. The power controller is a controller in a mainboard to which the N-phase power supply is connected, and the user controls the operation logic of the power supply.

请参见图2，图2示意了VR(Voltage Regulator，电压调节器)类型的三相电源中的其中一相电流PWM1的跳变波形。如图2所示，该相电流在单一开关周期内存在2次跳变：A→B和B→C；或B→C和C→D。考虑到采样起始点难以与跳变位置(如A、B、C、D点)保持重合，因此取2+1作为VR类型的三相电源的某一相电流在单一开关周期内脉动次数。例如：采样起始点为AB的中点E，那么单一开关周期的采样结束位置即为CD的中点F，在此单一开关周期内就存在3次跳变：E→B、B→C、C→F。据此可确定，VR类型的N相电源的某一相电流在单一开关周期内的脉动次数最多为N。Please refer to Figure 2, which shows the jump waveform of one phase current PWM1 in a three-phase power supply of VR (Voltage Regulator) type. As shown in Figure 2, the phase current has two jumps in a single switching cycle: A→B and B→C; or B→C and C→D. Considering that it is difficult for the sampling starting point to coincide with the jump position (such as points A, B, C, and D), 2+1 is taken as the number of pulsations of a phase current of a VR type three-phase power supply in a single switching cycle. For example: the sampling starting point is the midpoint E of AB, then the sampling end position of a single switching cycle is the midpoint F of CD, and there are 3 jumps in this single switching cycle: E→B, B→C, and C→F. Based on this, it can be determined that the maximum number of pulsations of a phase current of a VR type N-phase power supply in a single switching cycle is N.

请参见图3，图3示意了TLVR(Trans-inductor Voltage Regulator，跨电感电压调节器)类型的三相电源中的其中一相电流PWM1的跳变波形。如图3所示，PWM1的跳变波形受电源中补偿电感lc的影响，该相电流在单一开关周期内存在6次跳动。同样，考虑到检测起始点难以与跳动位置保持重合，因此取6+1作为TLVR类型的三相电源的某一相电流在单一开关周期内脉动次数。据此可确定，TLVR类型的N相电源的某一相电流在单一开关周期内的脉动次数最多为2N+1。那么在某一N相电源的单相电流在单一开关周期内的电流跳变次数大于N+1时，其必定不是VR类型的N相电源，而是TLVR类型的N相电源。反之，在某一N相电源的单相电流在单一开关周期内的电流跳变次数不大于N+1时，其必定不是TLVR类型的N相电源，而是VR类型的N相电源。本实施例据此可判定电源是TLVR类型还是VR类型。Please refer to Figure 3, which illustrates the jump waveform of one of the phase currents PWM1 in a TLVR (Trans-inductor Voltage Regulator) type three-phase power supply. As shown in Figure 3, the jump waveform of PWM1 is affected by the compensation inductor lc in the power supply, and the phase current jumps 6 times in a single switching cycle. Similarly, considering that it is difficult for the detection starting point to coincide with the jump position, 6+1 is taken as the number of pulsations of a phase current of a TLVR type three-phase power supply in a single switching cycle. Based on this, it can be determined that the number of pulsations of a phase current of a TLVR type N-phase power supply in a single switching cycle is at most 2N+1. Then, when the number of current jumps of a single-phase current of a certain N-phase power supply in a single switching cycle is greater than N+1, it must not be a VR type N-phase power supply, but a TLVR type N-phase power supply. Conversely, in a single phase current of a certain N-phase power supply When the number of current jumps of the phase current in a single switching cycle is not greater than N+1, it is definitely not a TLVR type N-phase power supply, but a VR type N-phase power supply. Based on this, this embodiment can determine whether the power supply is a TLVR type or a VR type.

其中，TLVR类型的电源相比于普通VR类型的电源大大改善了动态响应，所需滤波电容小，能够降低成本。如图4所示，TLVR类型的N相电源包括N个变压器：T1～TN，每一变压器的初级线圈的一端连接上下两个MOS(又称MOS管，MOSFET，Metal Oxide Semiconductor Field Effect Transistor，金属氧化物半导体型场效应管)，另一端连接输出Vout，N个变压器的次级线圈串联在一起，然后连接补偿电感Lc。如图5所示，VR类型的N相电源包括N个电感：lc1～lcN，N个电感的一端连接上下两个MOS，另一端连接输出Vout。Among them, the TLVR type power supply greatly improves the dynamic response compared to the ordinary VR type power supply, requires less filter capacitance, and can reduce costs. As shown in Figure 4, the TLVR type N-phase power supply includes N transformers: T1~TN, one end of the primary coil of each transformer is connected to the upper and lower MOS (also known as MOS tube, MOSFET, Metal Oxide Semiconductor Field Effect Transistor, Metal Oxide Semiconductor Field Effect Transistor), and the other end is connected to the output Vout. The secondary coils of the N transformers are connected in series and then connected to the compensation inductor Lc. As shown in Figure 5, the VR type N-phase power supply includes N inductors: lc1~lcN, one end of the N inductors is connected to the upper and lower MOS, and the other end is connected to the output Vout.

That is, on the line segment AB shown in FIG2 , at least two data points need to be sampled so as to determine the current direction based on the at least two data points.

If the sampling data in the sampling sequence are arranged in the order of sampling: S ₀ , S ₁ , ..., S _M-1 , then the difference sequence can be: S ₀ -S ₁ , S ₁ -S ₂ ..., S _M-2 -S _M-1 or S ₁ -S ₀ , S ₂ -S ₁ ..., S _M-1 -S _M-2 . M is the number of sampling data within a single switching cycle.

可见，本实施例能够利用电源控制器自动检测N相电源中的任一相目标电流在单一开关周期内的采样序列，然后基于采样序列可以确定该单相目标电流在单一开关周期内的脉动次数，也就确定了该单相目标电流在单一开关周期内的电流跳变次数；在脉动次数大于N+1的情况下，确定N相电源为TLVR类型的N相电源。因为TLVR类型的N相电源的单相电流在单一开关周期内的电流跳变次数最多为2N+1，而VR类型的N相电源的单相电流在单一开关周期内的电流跳变次数最多为N。因此在某一N相电源的单相电流在单一开关周期内的电流跳变次数大于N+1时，其必定不是VR类型的N相电源，而是TLVR类型的N相电源。据此，本申请可自动检测出电源的类型，而无需人工参与，因此可以提升检测效率和准确性，也能够为电源配置提供前提基础。It can be seen that the present embodiment can utilize the power supply controller to automatically detect the sampling sequence of the target current of any phase in the N-phase power supply within a single switching cycle, and then determine the number of pulsations of the single-phase target current within a single switching cycle based on the sampling sequence, and thus determine the number of current jumps of the single-phase target current within a single switching cycle; when the number of pulsations is greater than N+1, determine that the N-phase power supply is a TLVR type N-phase power supply. Because the number of current jumps of the single-phase current of the TLVR type N-phase power supply within a single switching cycle is at most 2N+1, and the number of current jumps of the single-phase current of the VR type N-phase power supply within a single switching cycle is at most N. Therefore, when the number of current jumps of the single-phase current of a certain N-phase power supply within a single switching cycle is greater than N+1, it must not be a VR type N-phase power supply, but a TLVR type N-phase power supply. Accordingly, the present application can automatically detect the type of power supply without manual intervention, thereby improving detection efficiency and accuracy, and can also provide a prerequisite for power supply configuration.

基于上述实施例，需要说明的是，三相普通VR电源在一个开关周期内，当其中一相电流PWM1对应的phase1的上桥臂打开、下桥臂关断时，电感承受正向电压，电感电流线性上升；当phase1的上桥臂关断、下桥臂打开时，电感承受负向电压，电感电流线性下降。上桥臂、下桥臂如图5中一个电感连接的上下两个MOS。因此三相普通VR电源在一个开关周期内，phase1(阶段1)电感电流先上升后下降，脉动次数为2。如果采样窗口的起始时间与PWM1的边沿时间不对齐，那么得到的脉动次数加1，变成3次。Based on the above embodiment, it should be noted that in a switching cycle of a three-phase ordinary VR power supply, when the upper bridge arm of phase1 corresponding to one phase current PWM1 is turned on and the lower bridge arm is turned off, the inductor is subjected to a positive voltage and the inductor current rises linearly; when the upper bridge arm of phase1 is turned off and the lower bridge arm is turned on, the inductor is subjected to a negative voltage and the inductor current decreases linearly. The upper bridge arm and the lower bridge arm are the upper and lower MOS connected to an inductor in Figure 5. Therefore, in a switching cycle of a three-phase ordinary VR power supply, the inductor current of phase1 (stage 1) rises first and then falls, and the number of pulsations is 2. If the start time of the sampling window is not aligned with the edge time of PWM1, the number of pulsations obtained is increased by 1, becoming 3 times.

相应地，三相TLVR电源在一个开关周期内，电感电流不仅受phase1的上下桥臂开关的影响，同时其他phase的上下桥臂开关信号也会通过变压器耦合过来。因此三相TLVR电源在一个开关周期内，phase1电感电流的脉动次数与补偿电感lc的电流脉动次数相同，如图3中的6次。据此可以推导出：N相TLVR电源的phase1电感电流的脉动次数为N*2次。同理，如果采样窗口的起始时间与PWM1的边沿时间不对齐，那么得到的脉动次数加1，变成N*2+1次。Correspondingly, in a switching cycle of the three-phase TLVR power supply, the inductor current is not only affected by the upper and lower bridge arm switches of phase 1, but also the upper and lower bridge arm switch signals of other phases are coupled through the transformer. Therefore, in a switching cycle of the three-phase TLVR power supply, the pulsation number of the phase 1 inductor current is the same as the current pulsation number of the compensation inductor lc, as shown in Figure 3. 6 times. Based on this, it can be deduced that the pulsation number of the phase 1 inductor current of the N-phase TLVR power supply is N*2 times. Similarly, if the start time of the sampling window is not aligned with the edge time of PWM1, the obtained pulsation number is increased by 1, becoming N*2+1 times.

综上可得出结论：对于N相电源，电源控制器可以通过采样phase1的电感电流波形，从而判断电感电流的脉动次数，之后可根据脉动次数区分电源是TLVR还是普通VR电源。由于存在采样误差，根据采样得到的电流脉动次数可能跟实际值有比较小的偏差。为了增强抗干扰性，本实施例设定判定条件为：对于N相电源(N≥2)，采样得到的某一相电感电流的脉动次数小于等于N+1，则判定是普通VR电源，大于N+1时判定是TLVR电源。In summary, it can be concluded that for an N-phase power supply, the power supply controller can determine the number of pulsations of the inductor current by sampling the inductor current waveform of phase 1, and then distinguish whether the power supply is a TLVR or ordinary VR power supply based on the number of pulsations. Due to the sampling error, the number of current pulsations obtained by sampling may have a relatively small deviation from the actual value. In order to enhance the anti-interference performance, the judgment condition is set in this embodiment as follows: for an N-phase power supply (N≥2), if the number of pulsations of the inductor current of a certain phase obtained by sampling is less than or equal to N+1, it is judged to be an ordinary VR power supply, and if it is greater than N+1, it is judged to be a TLVR power supply.

在一些实施例中，对于N相电源(N≥2)，假设一个开关周期内的采样点为M个，则有：In some embodiments, for an N-phase power supply (N≥2), assuming that there are M sampling points in one switching cycle, then:

(1)电源控制器判断某一相电感电流的采样点数是否满M个，如果是，继续步骤(2)，否则，继续进行采样；(1) The power supply controller determines whether the number of sampling points of a certain phase inductor current is M. If yes, proceed to step (2); otherwise, continue sampling;

(2)将M个采样点标记为S₀，S₁，…，S_M-1；(2) Mark the M sampling points as S ₀ , S ₁ , …, S _M-1 ;

(3)相邻采样点的前者减去后者，得到S₀-S₁，S₁-S₂…，S_M-2-S_M-1；(3) Subtract the adjacent sampling points from the former to obtain S ₀ -S ₁ , S ₁ -S _{2 ,} ..., S _M-2 -S _M-1 ;

(4)相邻差值做乘法，得到的各个乘积记为：X₀，X₁，…，X_M-3；(4) Multiply adjacent differences, and the resulting products are recorded as: X ₀ , X ₁ , ..., X _M-3 ;

(5)统计X₀，X₁，…，X_M-3中负数的个数，然后使负数的个数加1，即可得到当前相电感电流的脉动次数；(5) Count the number of negative numbers in X ₀ , X ₁ , …, X _M-3 , and then add 1 to the number of negative numbers to obtain the pulsation number of the current phase inductor current;

(6)脉动次数小于等于N+1，判定是普通VR电源，大于N+1判定是TLVR电源。(6) If the number of pulsations is less than or equal to N+1, it is determined to be a normal VR power supply; if it is greater than N+1, it is determined to be a TLVR power supply.

请参见图6，以7相TLVR电源或普通VR电源为例，假设电源控制器在每个开关周期内对phase1电感电流的采样次数为40，那么可选的检测流程包括：持续采样得到40个采样值，记为：S₀，S₁，…，S₃₉，相邻采样值做减法，然后相邻的减法结果做乘法，统计乘法结果中的负数个数，统计结果加1得到电流的脉动次数。脉动次数小于等于8，判定是普通VR电源，大于8判定是TLVR电源。 Please refer to Figure 6. Taking a 7-phase TLVR power supply or a common VR power supply as an example, assuming that the power supply controller samples the phase 1 inductor current 40 times in each switching cycle, the optional detection process includes: continuously sampling to obtain 40 sampling values, recorded as: S ₀ , S ₁ , ..., S ₃₉ , subtracting adjacent sampling values, and then multiplying adjacent subtraction results, counting the number of negative numbers in the multiplication result, and adding 1 to the statistical result to obtain the number of current pulsations. If the number of pulsations is less than or equal to 8, it is determined to be a common VR power supply, and if it is greater than 8, it is determined to be a TLVR power supply.

可见，本实施例得到采样序列后，通过对相邻采样值做减法，然后对相邻的减法结果做乘法，对乘法结果进行负数统计，统计结果加1就是电流的脉动次数。由此，借助电源控制器来计算一个开关周期内单相电感电流的脉动次数来区分TLVR与普通VR，不需要搭建额外的检测电路，方法简便高效。It can be seen that after obtaining the sampling sequence, this embodiment subtracts adjacent sampling values, then multiplies adjacent subtraction results, performs negative statistics on the multiplication results, and the statistical result plus 1 is the number of current pulsations. Therefore, the power supply controller is used to calculate the number of pulsations of the single-phase inductor current in a switching cycle to distinguish TLVR from ordinary VR, without the need to build an additional detection circuit, and the method is simple and efficient.
