초록
Recently, Power Electronics system increase makes harmonics and low input power factor problem. In this paper present new analysis method of PWM Boost AC/DC Converter. This PWM AC/DC Converter is capability of unity power factor, control of DC side voltage level, generation, and near sinusoidal current in 3-phase line. The control of this type of converter is widely discussed. And this paper propose new phase convert function and analysis in steady state of system to obtain amplitude and phaser of switching function. This switching function is general solution and it can use in high power approach. And this control method show the clear meaning of control variable. This paper propose new analysis method of Boost AC/DC Converter of steady state and 3-phase 2KW experimental system show its validity.
