一种谐振直流环节逆变器的建模与校正

Modeling and Compensation of a Resonant DC Link Inverter

针对工作在电流型三态离散脉冲调制方式的一种谐振直流环节逆变器———软开关组合式逆变器， 建立了其电流环等效解析模型，建模方法可推广于其它调制方式的双环瞬时反馈逆变器．研究了电压调节器的设计，并给出了设计实例和仿真结果．

Inner current loop modeling of a kind of resonant DC link inverter,soft switching combination inverter,which works in current controlled three state discrete pulse modulation mode,is proposed.The modeling method is valid for double loop feedback controlled inverters which works in other modulation mode. Equivalent analytic model is established and used for voltage regulator design. Examples are given in the end of the paper.
