  • Patent number: 7869236
    Abstract: A matrix converter includes a plurality of switches that electrically connect a multi-phase input voltage source to a multi-phase load; and a controller to output pulse-width modulated (PWM) switching signals to control the switches to produce a multi-phase output voltage from the multi-phase input voltage source. The controller outputs the PWM switching signals by modulating a carrier signal with a time-varying signal having a frequency determined from a desired output frequency for the output voltage.
    Type: Grant
    Filed: May 22, 2007
    Date of Patent: January 11, 2011
    Assignee: Regents of the University of Minnesota
