A Study on the novel voltage converter for PWM control method

PWM 제어방식에 의한 새로운 전압형 컨버어터에 관한 연구

This paper describes the voltage type PWM converter. Input AC current is to be sinusoidal and AC input voltage is determined by controlling the phase of the source and converter properly. By corresponding the phase of input voltage to that of base current, DC constant voltage Is to be output with high power factor driving. Also it is possible to be leading or lagging power factor driving. Optimum driving is performed by controlling the current instantaneously in the steady state or transient state.
