Power factor correction of the three phase boost converter using space vector PWM strategy
공간 벡터 PWM 법을 적용한 3상 boost 콘버터의 역률개선
Abstract
In this paper, three-phase PWM AC to DC boost converter that operates with unity power factor and sinusodial input line currents is presented. The current control of this converter is based on the space vector PWM strategy with fixed switching frequency and the line currents track to reference currents within one sampling time interval. By using this control strategy low ripples in the outut current and the voltage as well as fast dynamic response are achieved with small dc link cpacitance employed.
