Abstract:
A multi-level inverter includes a direct current input, a first bidirectional switch, a second bidirectional switch, a third capacitor, and an inverter. The direct current input includes a first capacitor and a second capacitor connected in series between positive and negative terminals of the direct current input power supply. The inverter includes a first switching tube, a second switching tube, a third switching tube, and a fourth switching tube that are connected in series co-directionally between the positive and negative terminals of the direct current input power supply. One terminal of the first bidirectional switch is connected to a connection point between the third switching tube and the fourth switching tube.
