一种新型有源箝位软开关三相并网逆变器
A Novel Active Clamping Soft Switching Grid-connected Three-phase Inverter
摘要
Abstract
A novel soft switching three-phase grid connected inverter was proposed.Through plug in a clamp branch,which consists of active switch,resonant inductor,and clamping capacitor into the dc link,zero voltage switching operation for all switching devices could be realized.Also the switch anti-parallel diode reverse recovery current was suppressed well.The switching voltage stress of all the power switch devices was equal to the DC link voltage.The modulation schemes and soft switching condition of this inverter were analyzed.The design guideline of the inverter was also analyzed.A 20？kW inverter prototype was built to verify the theory.关键词
