A novel sine wave in AC to DC converter with high frequency transformer isolation

摘要

A novel Switch-Mode-Rectifier (SMR) Structure is proposed and analyzed in this paper. The proposed converter structure employs a High-Frequency Sine PWM cycloconverter to provide high frequency ohmic isolation between the source and the load. Furthermore, it draws high quality current from the AC source thus requiring only small input reactive components. Consequently, the proposed converter structure exhibits high power density and has low implementation cost.
