Device and Method for Controlling Switch Module, Three-Phase Inverter and Program Product

원문 (중국어)

A device and method for controlling a switch module, a three-phase inverter, and a program product are disclosed. The switch module includes a plurality of switches in parallel. The device for controlling the switch module includes (i) a current acquisition module configured to acquire a total expected current flowing through a plurality of switches of the switch module, (ii) a power loss determination module configured to determine a plurality of power losses of a plurality of switch combinations when at least one switch of the plurality of switches is turned on based on the total expected current acquired, and (iii) a turn-on switch number determination module configured to determine a target number of the switches turned on for the total expected current based on the plurality of power losses determined. The device for controlling the switch module according to the present disclosure is capable of changing the number of switches turned on in the plurality of switches according to the total expected current to achieve a lower switch power loss.
