Abstract :
A zero-voltage-switched full-bridge regulator, with a switch frequency of 500 kHz, converts a 270 VDC input to an output voltage that is modulated between 22.5 volts and less than one volt. The small-signal reference-to-output bandwidth is greater than 60 kHz. Synchronous rectification allows the converter to source and sink output current
