인버터 용접기용 3상 SMR의 운전특성에 관한 연구
A Study on Operation Characteristics of 3-Phase SMR for Inverter Welding System.
초록
One of the drawbacks of using diode-bridge rectifiers in the unity interface, is the line-current harmonic distortion caused by the nonlinear nature of the rectifier operation. So, a PWM converter for the power factor correction is analysed for unity power factor as well as low cost design, which enable to meet the limits of international standards.
