Abstract
A DC-side soft switching device for a converter includes a battery, a bus capacitor, a first relay switch, a first resistor, a second relay switch, a second resistor, and a third resistor. The first relay switch is arranged between an anode of the battery and the bus capacitor. The first resistor is electrically connected in parallel to the first relay switch. The second relay switch is arranged between a cathode of the battery and the bus capacitor. The second resistor is electrically connected in parallel to the second relay switch. The third resistor is electrically connected in parallel to the bus capacitor.
