Design of Single-Phase Unity Power Factor High Efficiency PWM Rectifier

단위역률을 갖는 고효율 PWM 단상 정류기의 설계

The paper describes a power factor correction high efficiency PWM single-phase rectifier. Its good characteristics such as simple circuit structure, simple PWM control, low switch stress, and low VAR rating of commutation circuits make the proposed rectifier very suitable for various unidirectional power applications. In particular, the design guide line is suggested to make the circuit design of the proposed rectifier easy and fast.
