Abstract The DC-side static and dynamic behaviours of SPWM 2H-bridge inverters which act as the typical DC-side loads in many AC/DC/AC converter systems, have important influences on researches on modeling, control approach and static and dynamic character of their front converters. Thereby, it is necessary to study the DC-side equivalent model of the inverters and consequently reveal the load characters relative to their front converter systems. Based on building the mathematic model of the inverters, this paper deduces a DC-side equivalent mathematic model. Finally, via a great deal simulations and experiments, the validity of the model and its approximate simplified equivalent circuit model are confirmed.

Key words： AC/DC/AC converter system SPWM 2H-bridge inverter DC-side equivalent model simplified equivalent circuit model
