A New current Controller implemented in a-b-c frame for AC-DC converter

a-b-c frame에서 구현한 AC-DCconverter 전류제어기

A new current controller implemented in a-b-c frame for AC-DC converter is proposed. The proposed MTPWM(Modified Trapezoidal PWM) Which is quite suitable for three phase AC-DC converter. It is known that MTPWM has good harmonics characteristics for high modulation index. It is very simple and requires no transformation in it. The results of computer simulation are shown for the validity of proosal.
