Control Circuit For Lossless Switching Converter

Control Circuit For Lossless Switching Converter

US Patent:
2007015, Jul 5, 2007
Filed:
Dec 30, 2005
Appl. No.:
11/323627
Inventors:
George Cebry - Glendale AZ, US
Ernest Graetz - Largo FL, US
Robert Johnson - Clearwater FL, US
Robert Tomlinson - Peoria AZ, US
International Classification:
H02M 3/335
US Classification:
363016000
Abstract:
A DC-to-DC converter comprises a converter section and a controller section. The converter section comprises a primary section and a secondary section. The primary and secondary section includes MOSFET switches. The controller section is coupled to the converter section and comprises a pulse width modulation (PWM) section and a delay section. The PWM section comprises an error amplifier configured to generate an error signal representative of a variance between an output voltage of the converter section and a reference voltage and a PWM configured to produce a PWM signal based on the error signal. The delay section comprises of delay circuits configured to generate delayed output signals from the PWM signal and power switching device drivers coupled to the delay circuits and configured to receive the delay output signals and generate a controlled signals to control the on/off state of the MOSFET switches.
