Abstract
A power conversion device includes a power conversion device includes an auxiliary power supply, a first load, a power conversion circuit, and a controller. When an output voltage of the auxiliary power supply in operation is greater than or equal to a first voltage threshold, the controller controls the first load to be connected to the power conversion device, so that the output voltage of the auxiliary power supply decreases. When the output voltage of the auxiliary power supply is greater than or equal to a second voltage threshold after the first load is connected to the power conversion device, the controller controls the first load to be disconnected from the power conversion device, and controls the output voltage of the auxiliary power supply to be a first target output voltage. The first voltage threshold is less than the second voltage threshold.
