  • Vector controller, a polyphase synchronous rectifier, and a method of vector-controlling thereof
    Patent number: 7129677
    Abstract: A vector controller for a polyphase synchronous rectifier, a method of vector-controlling a polyphase synchronous rectifier, and a synchronous rectifier incorporating the vector controller or the method. In one embodiment, the vector controller includes: (1) an input line voltage detector configured to detect voltages on at least two rectifier input lines and produce therefrom a neutral excursion vector and (2) a neutral excursion compensator, coupled to said input line voltage detector, that applies said neutral excursion vector to a partially compensated drive vector to yield an excursion-compensated drive vector suitable for generation of excursion-compensated pulse-width modulated drive signals for said synchronous rectifier.

  • System and method for increasing effective pulse-width modulated drive signal resolution and converter controller incorporating the same
    Patent number: 6965260
    Abstract: A system for, and method of, increasing effective pulse-width modulated (PWM) drive signal resolution and a power converter incorporating the system or the method. In one embodiment, the system includes: (1) a duty cycle calculator configured to calculate a theoretical duty cycle for a PWM drive signal to be provided to an associated power converter based on at least one operating condition thereof, the theoretical duty cycle not a member of a pre-established set of allowable duty cycles and (2) a duty cycle approximator coupled to the duty cycle calculator and configured to generate a sequence of members of the set of allowable duty cycles, wherein the sequence at least approximately averages to the theoretical duty cycle.
