Abstract
Provided is a multi-level inverter, which includes a first bus capacitor, a second bus capacitor, a third bus capacitor, a fourth bus capacitor, a seventh switch unit, an eighth switch unit, an inverter circuit and a filtering circuit. The first bus capacitor, the second bus capacitor, the third bus capacitor and the fourth bus capacitor are connected between a positive direct current bus and a negative direct current bus in series, and a series point between the second bus capacitor and the third bus capacitor is grounded. The switch transistor of the anti-parallel diode having small on-state resistance is used in the multi-level inverter, thereby reducing power loss of the switch unit in the multi-level inverter and reducing power consumption of the circuit.
