For example, the first power supply unit 131 inputs an alternating current, and obtains a direct current with a voltage of 310V through filtering and rectification.
For example, the second voltage unit 132 forms a BUCK step-down circuit by using a switching power supply chip, an inductor, a diode, and a capacitor, and performs step-down processing on the direct current with the voltage of 310V to obtain the direct current with the voltage of 15V. The 15V dc power can be output to the driving module 120, for example, to the plurality of voltage inversion driving modules 1211 in the driving module 120.

In the case where the main control board generates a plurality of control instructions, the main control board sequentially transmits the plurality of control instructions to the integrated control board 100, that is, the processor module 110 performs time-division communication with the main control board.
For example, the control instruction includes an operation parameter and an operation time of the load. For example, for a motor, the control command includes the rotation speed, the steering, the operation time, and the like of the motor.
In an implementation manner of the embodiment of the present invention, the communication module 140 may have an optical coupler, which isolates strong and weak current between the integrated control board 100 and the main control board. The number of optical couplers may be determined according to actual needs, for example, the communication module 140 has two optical couplers.
In an implementation manner of the embodiment of the present invention, as shown in fig. 5, the power module 130 further includes:
a third power supply unit 133 that steps down the direct current having the second voltage output from the second power supply unit 132 and outputs the direct current having a third voltage to the processor module 110 and/or the communication module 140.

For example, the third power supply unit 133 steps down the 15V dc power output by the second power supply unit 132 to obtain a 3.3V or 5V dc power, and the processor module 110 and/or the communication module 140 outputs the 3.3V or 5V dc power.
In this way, the power supply module 130 can supply power to each module requiring power supply in the integrated control board 100.
