New Description: [New Technology Field] This creation is about a current suppression balance circuit, especially a current transformer that uses a balance transformer to compare the current at each load end with a stable (calibrated) current.俾 to achieve the effect of controlling the stability of the load and balancing the current. [Prior Art] In the general LCD panel, it is often necessary to use a plurality of lamps f to provide sufficient brightness, so that the power supply for the above lamps can be driven by a single panel or other power conversion system. Two or more lamps connected in parallel, due to the difference in impedance between the lamps, will seriously affect the distribution of the current (shunt) flowing through each parallel lamp, so that the current is cut, (or 敎) and the brightness is caused. Insufficient (or over-exemption)', which in turn affects the uniformity of the light source of the liquid crystal display panel. Secondly, if the current is too large, the service life of the lamp itself and the whole system will be shortened. Moreover, the component error of the converter and the special lamp of the inverter will be activated first. After the tube current increases, the tube voltage is relatively reduced, and the other parallel connection ^: because the input has been recorded to the residual electricity can not be paste started, and even the panel produces flashing its main ^ disclosure ^ country flip bulletin bulletin number 478292 "Multi-lamp drive « unified" invention patent case, the power supply, and balance L type from the output load end of the early converter, using the principle of impedance matching to achieve the purpose of the lamp ant, but the above system, Qing _ Then, the other sub-lights are sequentially matched with the main lamp, and the main U is still in the process of the main U, and there is still a process that cannot be calculated, and the difference is too small, and because of it The difference between the lamp factory's strength, electrode coating, etc., the length of the pipe, the length of the tube, the density of the mercury, and the shift, which leads to the partiality of the internal resistance characteristic curve of the tube current. Each lamp is maintained in the best working condition, and its balance current M291174 effect, = 'how to remove the above missing, and provide - fine balance followed by each load 2 and == and - 敎 (fresh The money is relatively simple, and it is expected that the work of "stationary work and stability" is the place where the technology is to be solved by human beings. Therefore, this kind of current suppression balance circuit is innovatively developed. [New content] The main purpose of a creation is to provide a balance of observation and suppression, which should be at least, such as: 赖 取, _, illuminating components (such as professional coffee light-emitting diodes) single-phase or In a multi-phase shunt high-power module (such as Multi_phase DC DC C read rter). ·.), the control loop includes: an inverter circuit for supplying current to the loads; ^ ^ then circuit ' To receive and detect the total load (or specified reference load) in its control loop. And after the current I is stabilized (rectified wave), it is fed back to the input end of the converter circuit for the converter circuit to output a stable (calibrated) current; a to more than one balance transformer, The primary side coil is configured to receive the stable (calibrated) current output by the switching/(10) circuit, and the secondary side thereof (3_(1&17 side) coils are used to individually connect the loads; In this case, under the application of Lenz's Law, that is, the direction of the induced potential is the direction of the anti-antigen magnetism and the good g minus, when the current of the secondary transformer of the balance transformer is mutated (ie The power of the load terminal is different (the difference is generated), which can be compared (synchronized) with the stable (calibrated) current of the primary side, so as to achieve the effect of controlling the stability of the load and balancing the current. M291174 Tree=More=Inspectors are convenient and simple to understand the other features and advantages of this creation and the achievements they have achieved are more obvious.

The current variation (ie, dis/dt) of the (secondary side) is proportional to, and also increases with the inductance of the secondary side (ie, LS), which means that the anti-electricity M291174 momentum (ie vs) will As the inductance (ie LS) of the ^(sec〇ndary side) is increased and the amplification is increased, the power is applied (suppressed) to the load of the balance transformer 3 on its secondary side side) L, the current of the secondary side (sec〇ndary side) of the balance transformer 3 is passed through the back electromotive force; k is allowed to go down, and the primary side thereof can be used (primary 3) The current of the current is fully balanced (matched) (ie, the primary side and the secondary side are inverted to cause the excitation of the individual currents to cancel each other out, and the balance is pressed to keep the core working in the unsaturated region and boost the inductance. The amount, while the secondary electromotive force generated by the secondary side current variability can be reversed and feedback can effectively stabilize the load work); thereby '(please refer to Figure 1) is the application implementation diagram of the creation, wherein, when The control loop starts the day, receives and detects the current amount (i〇) of the total load 4 in the control loop through the detection circuit 2, and after the current s is stabilized, it is fed back to the input of the converter circuit End, the converter circuit 丨 outputs a stable (calibrated) current to pass through the balance transformer 3 to the load 4 end, such that (under the application of the theorem), if the balance transformer 3 has its secondary side When the current is mutated (that is, when the current at the end of the load is mutated), the secondary side end of the balance transformer 3 (ie, the end of the load 4) can generate a counter electromotive force for stabilization with the primary side thereof (calibration) )Electricity Comparing (matching), in order to effectively suppress the generation of the secondary side of the secondary side (ie, the load 4 end), in order to achieve the effect of controlling the stability of the fine and balanced current, and at the same time, further The balance transformer 3 has the characteristics of its back electromotive force, so that its undriven (lighted) load 4 can force its voltage to enter the driving (lighting) state, thereby effectively controlling the driving (lighting) of each load 4.
