A platform for inverter system research based on semi-physical simulation

A novel semi-physical simulation platform for inverter is proposed. The driving circuit and SPWM bridge are replaced by a low power level circuits of operational amplifier and logic ICs, and DSP controller exactly the same with that for the real system. The semi-physical simulation platform can be used for system-level research, especially for control algorithm design, with equivalent inverter system’s control-characteristics and greatly reduced power rating. The analysis and design of the platform mentioned are presented in detail with simulation and experimental result given.
