Servo power module

Abstract

The invention relates to a servo power module. The servo power module includes a power module set and a discharge circuit, wherein the power module set is composed of multiple power modules connected in series, each power module has different voltage and power outputs, the multiple power modules are combined in series, so the relatively large voltage and power outputs can be achieved by the power module set, the limitation of the high power output of the servo power module in the prior art can be overcome, the servo power module is made to have relatively high power density, instantaneous power output capacity is improved, and power input requirements of a motor are met. In addition, the servo power module has high power density, so the size and the weight of the servo power module can be reduced, moreover, the servo power module is provided with the discharge circuit, a pumping voltage generated by the motor superposed at an output end of the power module set can be suppressed, stability of the output end voltage of the servo power module is guaranteed, and thereby stability of power supply of a latter device is further guaranteed.
