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 5):
The four-level inverter topology unit of  claim 1 , further comprises a first circuit module and a second circuit module which has input terminals connected to the first circuit module; wherein the second circuit module comprises the floating capacitor;\n the first circuit module provides at least two circuit branches: one circuit branch is connected between the first DC power supply and one input terminal of the second circuit module, and the other is connected between the second DC power supply and another input terminal of the second circuit module; the two circuit branches are extended to the floating capacitor inside of the second circuit module; the second circuit module produces four mutually different voltage levels.
