Carrier-Based Pulse-Width Modulation (Pwm) Control For Matrix Converters

View page

US Patent:

7869236, Jan 11, 2011

Filed:

May 22, 2007

Appl. No.:

11/752110

Inventors:

Ned Mohan - Saint Paul MN, US
Krushna K. Mohapatra - Minneapolis MN, US
Satish Thuta - Minneapolis MN, US
Gaurav K. Aggarwal - Minneapolis MN, US
Philip Jose - Moshi, IN

Assignee:

Regents of the University of Minnesota - St. Paul MN

International Classification:

H02M 7/5387

US Classification:

363132

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.

Constant Frequency Resonant Power Converter With Zero Voltage Switching

US Patent:

48558885, Aug 8, 1989

Filed:

Oct 19, 1988

Appl. No.:

7/259673

Inventors:

Christopher P. Henze - Eagan MN
Ned Mohan - Minneapolis MN
John G. Hayes - Camarillo CA

Assignee:

Unisys Corporation - Blue Bell PA

International Classification:

H02M 3335

US Classification:

363 17

Abstract:

A full bridge DC-DC series-resonant power converter is operated at a constant switching frequency using a phase delay between the transistor legs of the bridge to control the output voltage. All power semiconductor devices switch on and switch off at approximately zero volts while operating at a constant switching frequency which is above the resonant frequency of the resonant tank circuit. Zero-voltage switching increases the efficiency of the power converter and allows high frequency operation which minimizes component volumes. Constant frequency operation simplifies design of the magnetic components, confines the EMI spectrum to known frequencies and simplifies EMI design, and reduces the voltage and current excursions and thus reduces the peak component stress.
