Abstract
A regulated hybrid AC-DC rectifier employing a boost stage is disclosed herein. The regulated hybrid AC-DC rectifier comprises a 12 pulse inductive current splitter/merger (CSM) system coupled to a boost stage. The boost stage may be regulated using a PWM controller. The regulated hybrid AC-DC rectifier may further include a three phase input filter configured to regulate the harmonic content of the AC-DC hybrid converter within a desired limit. The regulated hybrid AC-DC rectifier may further comprise a notch filter system configured to tune out harmonic ripples at known intervals, such as 11and 13order harmonics.
