新型零电流开关谐振极型逆变器
Novel Zero-current Switching Resonant Pole Inverter
摘要
Abstract
A novel resonant pole inverter in which switches could achieve zero-current soft transition was proposed to improve the efficiency and reduce the auxiliary resonant circuit loss. The structure of the auxiliary circuit was simple and the control was convenient. Each phase of the inverter only had two auxiliary switches, one resonant inductor and one resonant capacitor in the auxiliary resonant circuit. Due to the resonant of the inductor and the capacitor, when the current through the switching devices was zero, the main switching devices and auxiliary switching devices of inverter could turn off under zero-current condition. The operation principle was analyzed based on the equivalent circuits at different operation stages. The conditions of soft-switching and the detailed process of parameter design were also achieved. A rating power 1kW one-phase inverter was built. The experimental results demonstrated that all main switching devices and auxiliary switching devices achieved soft-switching transition and the efficiency compared with hard-switching inverter was improved effectively.关键词
