The induction electromotive force unit 21 and the reverse electromotive force unit 22 start to monitor the electromotive force changes during the start and stop process of the motor. The electromagnetic interference prevention unit 23 starts to reduce the influence of external EMI. The soft start unit 31 controls the current rise rate of the power module 1 according to the data of the real-time monitoring unit 2 to avoid the start-up impact. If the real-time monitoring unit 2 detects an abnormal situation, such as voltage transient, the transient voltage suppression unit 32 responds quickly to absorb overvoltage, and the filtering protection unit 33 starts to filter out the clutter and interference in the power supply to improve the purity of the power supply. When the real-time monitoring unit 2 detects a load change, the multi-stage buffer unit 34 runs to buffer the impact on the power supply when the load changes suddenly. When the load demand suddenly increases, the energy storage unit in the energy storage and recovery unit 35 quickly releases the stored energy to supplement the output of the power supply. When the load changes frequently, the recovery unit absorbs instantaneous excess energy.
