英文摘要	The structure of inverter units connected in series has been widely applied to the reactive power compensation, frequency control of motor speed and renewable energy power generation system. The correlation and constraints among units make it very difficult to enquire the dc-side respective equivalent model of the unit. Firstly, this paper has established the voltage and current mathematical relationship of H bridge inverter units between DC and AC side. Secondly, equivalent models on the DC side of inverter units are obtained under different modulation strategy, and the relationship of DC side equivalent model among H-bridge inverters is analyzed. Finally, considering the complexity of the model, the simplified equivalent model is given. Simulation and experiment results validate the correctness of the model. ©, 2015, The editorial office of Transaction of China Electrotechnical Society. All right reserved.
