Summary: | A conversion apparatus with a three-level switching circuit includes a DC conversion module, a three-level circuit, and a control unit. The three-level circuit includes a bridge arm assembly and a capacitor assembly. The capacitor assembly includes a first capacitor and a second capacitor connected to the first capacitor in series. The DC conversion module has a positive output end and a negative output end, and the positive output end and the negative output end are coupled to the bridge arm assembly. The control unit controls the switching of a second switch unit and a third switch unit to make the three-level circuit operate in a first state where the positive output end and the negative output end are connected to the first capacitor, and operate in a second state where the positive output end and the negative output end are connected to the second capacitor. |
