Abstract

A control power supply device for an inverter includes a main switched-mode power supply, SMPS, (120) for supplying rated voltages to a controller and an auxiliary circuit of the inverter, an auxiliary SMPS (130) configured to be operated when the main SMPS (120) is interrupted to supply the rated voltages to the controller and the auxiliary circuit of the inverter ; and an SMPS controller (140) configured to sense an output voltage from the main SMPS (120), determine whether the sensed voltage is within a normal range and interrupt the main SMPS (120) and operate the auxiliary SMPS (130) if not, and transmit trip information to the controller (14).
