Implementation of a three-level inverter based on zig-zag connected transformer using selective harmonic elimination

碩士 === 國立臺灣科技大學 === 電機工程系 === 95 === This thesis applies the zig-zag transformer and the selective harmonics elimination PWM (SHEPWM) scheme to control a three-level inverter system. The PWM is designed to a quarter symmetry wave due the transformer’s characteristics. The wave applies the Newton-Rap...
