Abstract

See full text

A single-stage three-phase voltage source inverter circuit structure with a cascaded magnetic integrated switching inductor-capacitor network includes an input DC power supply, a magnetic integrated switching inductor-capacitor network, a three-phase inverter bridge, a three-phase filter, a three-phase AC load or a three-phase AC grid successively connected in cascade. The magnetic integrated switching inductor-capacitor network includes an energy storage inductor, and two identical SLCC type two-port switching inductor-capacitor network units which are successively connected in cascade and connected in series. A magnetic integration structure of the three energy storage inductors is configured to have magnetic coupling of the three inductors, magnetic decoupling of the three inductors, or magnetic coupling of each inductor with the other two inductors, which are respectively realized by an EE type magnetic core, a four-leg type magnetic core, and an EE type magnetic core.
