Abstract:
Power conversion systems and operating methods are presented in which an active front end rectifier is operated in a boost mode using discontinuous pulse width modulation in a first range of DC bus voltage boost amount, and continuous space vector pulse width modulation is used in a second range, with the ranges being correlated to output derating with respect to filter inductor magnetics in the first range and to rectifier switching loss derating and the second range.
