A CRPWM Boost Type AC/DC Converter based on Modified Trapezoidal PWM

Modified Trapezoidal PWM을 베이스로 한 CRPWM Boost Type AC/DC Converter

This paper describes a current regulated PWM boost type rectifier based on modified trapezoidal PWM. Each switch of a converter has no switching for one third period of a fundamental line current. Therefore, the switching loss of the proposed scheme is less than that of the hysteresis current controller. Operating principle is described and controller. Operating principle is described and simulations and experiments are carried out.
