Abstract:
A single-phase four-level inverter circuit topology and a three-phase four-level inverter circuit topology. The single-phase four-level inverter circuit topology is adapted to be used with two series-connected direct current power sources, so as to enable a first direct current power source or a second direct current power source to supply power to a load of the four-level inverter circuit topology, alternatively, any one of two direct current power sources is first algebraically superimposed with a flying capacitor and then supplies the power to the load of the four-level inverter circuit topology (M), thereby making the four-level inverter circuit topology output four different levels. The single-phase and three-phase four-level inverter circuit topologies reduce the system cost and volume by using a flying capacitor, the voltage utilization rate is three times that of the existing four-level inverter circuit topology under the same operating conditions, and the direct current side neutral point voltage can be balanced without requiring additional circuits.

Claim (Index 10):
The four-level inverter topology unit of  claim 8 , wherein the first circuit module further comprises a current limiting device, such as an inductor, resistor, semiconductor device operated at active mode or linear mode, or the combination of the above devices.
