An electrical energy router includes cascaded submodules. Each submodule of the cascaded submodules includes a rectifying stage and an isolating stage. The rectifying stage includes a structure of a neutral point clamped full bridge. The isolating stage includes a DC-DC converter, which includes a primary side, a secondary side and a transformer. The primary side includes a structure of a neutral point clamped half bridge. A DC side of the neutral point clamped half bridge is connected to a DC bus line of the rectifying stage.

An IGBT modeling method includes creating piece-wise line functions describing a collector-emitter voltage v, a collector current iand a gate-emitter voltage vof the IGBT during a switching-on transient based on an internal structure of the IGBT and transient processes of the IGBT. The IGBT modeling method further includes creating piece-wise line functions describing the collector-emitter voltage v, the collector current iand the gate-emitter voltage vof the IGBT during a switching-off transient based on the internal structure of the IGBT and the transient processes.
