The power processing system 1001 mainly undertakes power monitoring of a high-voltage system and a high-low voltage conversion system, guarantees power supply and working state indication of the system, and firstly needs to guarantee the safety of a power supply system in order to improve the safety of the system. The system is different from the traditional kitchen electrical system in that a power supply system not only provides power energy for a load, but also is a work guarantee of a control system 1002, so that the design must guarantee that the linkage fault of the control system 1002 cannot be influenced by the fault of the power supply system, if the control system 1002 has the power supply fault, a display screen fault user cannot know where the system is in a problem, the power supply system of the control system 1002 can also cause the failure of drive output, the load drive is out of control, and the like. Therefore, the power supply system is promoted from the original single power supply requirement to the power supply 'processing' system.

Referring to fig. 8, the power processing system 1001 includes a dc power supply main circuit for supplying power to the dc driving system 1003 and an ac power supply main circuit for supplying power to the ac driving system 1004, one end of each of the first voltage reduction module, the second voltage reduction module and the voltage reduction module BKP (control register) is connected in parallel to the dc power supply main circuit, and the other end of each of the first voltage reduction module, the second voltage reduction module and the voltage reduction module BKP respectively supplies power to the control system 1002 through one 500mA isolation module, and outputs 12V low voltage power. The main AC power supply circuit can output 12V low voltage electricity after the action of the rectifying circuit and the voltage stabilizing circuit.

And a Delay control switch Delay is also arranged between the voltage reduction module BKP and the direct current power supply main circuit and is used for controlling the start and stop of the voltage reduction module BKP.

The power processing system 1001 is designed with a three-way parallel low-voltage power system, wherein the first voltage reduction module and the second voltage reduction module are two completely independent systems, and the control system 1002 can work when any one voltage reduction module is required to supply power normally in the design. The voltage reduction module BKP is a backup power supply system under the condition that the first voltage reduction module and the second voltage reduction module are both in failure, and operates as a system guarantee.

Meanwhile, the first voltage reduction module and the second voltage reduction module also output low-voltage power supplies, namely 12V1 and 12V2, the output voltage of the voltage reduction module BKP is 12V BKP, but the time delay power supplies of 12V1 and 12V2 are realized in time sequence, namely the time delay of the power supply time sequence is the time delay. In the present embodiment, 50ms (time adjustable) is designed. Within 50ms, the Delay control switch Delay is in a Close state, and after 50ms, if the control system 1002 gives an Open switch signal, the 12V BKP is turned off, on one hand, because the control system 1002 can give an Open signal to indicate that the control system 1002 is normal, the standby 12V BKP power supply is not needed, and on the other hand, the hardware life of the standby power supply is also prolonged.

The control signal is a destructive 'flag control' of the 12V power supply system, that is, the control signal is output by the control system 1002, which proves that the 12V power supply is normal, and the red 12V power supply always keeps working output if the control signal cannot be provided, so as to ensure that the control system 1002 works when power is supplied.

Referring to fig. 10, the enable signal can supply power to the control system 1002 to ensure the safe operation of the control system 1002. If the control system 1002 is not started within 50ms in the design, the capacitor C1 gradually reaches the start threshold value due to the accumulation effect of the capacitor charges, so that the Delay control switch Delay is started, the voltage reduction module BKP is started, and the control system 1002 can work.

Pin 2 of the high voltage isolator U1 is connected to pin 3 of the high voltage isolator U2, and pin 3 of the high voltage isolator U1 is connected to pin 2 of the high voltage isolator U2.

Referring to fig. 14, in the present embodiment, through the arrangement of the isolation circuit, the pulse signal PWM1 and the pulse signal PWM2 are two complementary signals, as shown in the figure, the complementary PWM sometimes needs to add a "dead zone" to prevent the two signals from being simultaneously 1 or 0, so as to ensure the safety of the IGBT output.

Referring to fig. 15, the dc driving system 1003 includes a first soft switch module, a first resistive load power driving module, a first H-bridge power driving module, a second H-bridge power driving module, a dc load, and a plurality of hall elements.
