Description of the invention (1) This case is a burner recovery unit, which is placed in the environment of a burner, as a load of the burner device, and recovers the energy consumed by the burner to save costs. 0 Generally available Electrical products that supply energy, such as power supplies, need to go through a burner (Burn-i η) step in the manufacturing process of the product to determine the quality of the product before repackaging and shipping. The method of burning in conventional technology can be referred to the diagram in Figure 1. The output of the product is connected to the maximum load of ~ 100% '. Then at a high temperature of 40 to 55 degrees Celsius, the burning can range from 4 to 24 hours to screen. Defective. From Figure 1, the schematic diagram of the burn-in method of the conventional technology, it can be seen that a set of resistive loads 12 must be connected to each power supply 1 1. Take the product model with the power supply 11 as 800 watts as an example, and the resistance load 12 as the resistance with 640 watts. Since each product requires a set of loads, it requires a lot of space to place many various devices when burning, and it is cumbersome and difficult to manage. In addition, the burner uses resistors as the load, so the energy consumed by the load is converted to heat and dissipated. In addition to causing extremely high temperatures in the plant and poor working environment for employees, it also wastes a lot of energy and costs. It also has adverse effects on environmental protection. Take a product of 800 watts (800 W) as an example: 8 0 0W x 8 0% load x 7 0 units (daily production capacity) = 448KW (energy consumption), 448KW X 1 2 hours (burning hours) X 5/7 (5 working days) X 365 days X0. 0022 (electricity per watt) = 3,083, 520 (single model wave per year

The unit body contains three parts: "It is used to receive the energy output from the product (previously ordered as electric direct current), and to damage the test and compare the energy (direct current). Not to be affected by abnormal product burn-in conditions, the conversion circuit 42 is a process that converts the output energy of the received product to provide input energy for other products. In the previous example, the conversion circuit was a shock A circuit to convert direct current to an alternating current; a relay circuit 43 is to output the energy converted by the conversion circuit to other products to supply the energy required for its burn-in. Figure 5 shows the implementation of the burn-in recovery unit. The detailed circuit diagram of the example. In Figure 5, the comparators U1A, U1B, U1C, U2B, and U2C on the left are used to test the three power supplies of PG 1, PG 2, and PG 3 respectively (p 〇werg ο od) Signal to The over voltage and under voltage of the DC input (Vin). In addition, the comparator U2A in the middle of the circuit diagram is used to detect the over current (0 vercurrent), and the temperature switch (T h 1) is used to detect Measure overheating (0 ver T herma 1). When one of the above three PG signals and overvoltage, low voltage, overcurrent and overheating are detected to be problematic, the potential of node DC-0FF is high, which makes the transistor Q1 is turned on, and the red light emitting diode (LED 1A) will emit red light, indicating a problem with the display system.

The polar body (LE D1 B) emits green light to show that the system is operating normally. At the same time, the low potential of node DC-0FF causes transistor Q5 to turn off (0f f) and transistor Q6 to turn on (ο η), so that the potential of the node + V θ s c becomes a high potential, causing the conversion circuit 42 to start to operate. The low potential of DC-OFF will also turn off the transistor (0ff), and then a high potential is output by the comparator U2D, so that the transistor Q8 is turned on (0n), and the potential of node K 2-C is changed to a low potential.

當燒機一開始時，前級電源供應器輸出的電源DC + 48/12Vin不直接接至DC Vin節點，而是先經過電阻R55的限流再接至DC V i η節點，以防止後級負載過重（例如短路）的大電流燒壞電路。當DC Vin的電位升上至一特定電位時 (由比較器U 2 C偵測），等一段電源的上升時間（r i s i ng time)之後，再藉由比較器u ID及電晶體Q4來驅動繼電器 K1，使DC Vin 與DC +48/12 Vin 短路。另外’ DC V i η又接至變壓器T2 —次側的中間點，提供固定的直流電壓，而變壓器左右的二對場效電晶體 Q23，Q25及Q24，Q26則會交換開啟（on)及關閉（off)，來使變壓器的二次側感應出交流電壓。如前所述，當一切偵測沒問題時，+Vosc節電會呈現高電位，這會致能電晶體〇23,〇24，卩25，卩26，（311，卩12，使這些電晶體接受振盪電路（由反向器U4B，U4A，U4D，U4E所組成）的控制。此時振盪電路會輸出方波控制Q12, Q24, Q2 6，而由反向器U4E產生一互補的方波信號控制Q11,Q23,Q25。When the burn-in is started, the DC + 48 / 12Vin output from the power supply of the previous stage is not directly connected to the DC Vin node, but is first connected to the DC V i η node through the current limitation of the resistor R55 to prevent the subsequent stage. Heavy currents (such as short circuits) can damage the circuit. When the potential of DC Vin rises to a specific potential (detected by comparator U 2 C), wait for a rise time (risi ng time) of the power supply, and then drive the relay by comparator u ID and transistor Q4 K1, short the DC Vin to DC +48/12 Vin. In addition, 'DC V i η is connected to the intermediate point of the transformer T2-secondary side to provide a fixed DC voltage, while the two pairs of field effect transistors Q23, Q25 and Q24, Q26 on the left and right of the transformer will be switched on and off. (Off) to cause an AC voltage to be induced on the secondary side of the transformer. As mentioned earlier, when everything is ok, the + Vosc power saving will show a high potential, which will enable the transistors θ23, 〇24, 卩 25, 卩 26, (311, 卩 12, so that these transistors will undergo oscillation Control of the circuit (consisting of inverters U4B, U4A, U4D, U4E). At this time, the oscillating circuit will output square wave control Q12, Q24, Q2 6, and the inverter U4E will generate a complementary square wave signal to control Q11. , Q23, Q25.

Description of the invention (8) When Q12, Q24, Q26 are on (on), another group of Q1 1, Q23, Q25 is off, so as to enable Transformer T2 induces AC voltage. At the beginning of the burn-in, there is no voltage at node K2 -C, transistor Q1 9 is turned off, and the power of 12Vcc is driven by resistor R44, diode D18, D19 to drive transistor Q20 'to make transistor Q20 on, One end of the coil of the relay k3 is connected to S ground, and the other end is connected to + 1 2Vcc ', so that the K3 contact is turned on (on), and the node K2-C without voltage at the same time makes the relay k2 inactive, so the burn-in-start The power output (AC Output) of each stage of the power supply is connected to the AC power (AC-N, AC-L) of the mains, and the mains provides the power. When everything is detected correctly, the relays of the transfer circuit 43 are used to connect the power (AC Ou t pu t) consumed by the various stages to the input transformer T2 of the previous stage. The AC power generated by the oscillation circuit is controlled. At this point, the power output from the previous stage can be recycled. In addition, the relay K 4 is also a protection circuit. When the voltage of the transformer 2 is output, it is not directly connected to the AC Output ', but the upper limit current is first connected. After a certain delay, it is determined that there is no problem. . In addition, the lower rectifier diode D23 'transformer η and the power integrated circuit ㈣, U5 are used to provide the system +/- 12 VDC. The other parts are for those who are familiar with the art to practice and understand, so I will not repeat them here. In summary, we can draw the following three conclusions: 1. Using the burner recovery unit in this case in the manufacturing process can effectively recover a large amount of energy wasted in conventional technology; and it reduces a lot of production costs. 2. The results of energy recovery in this case can reduce the waste of energy and have great benefits for environmental protection. It can be said to be an advanced idea in line with the trend of the times. Third, too fool with f
