A new class of pulsewidth-modulated multi-resonant converters using resonant inductor freewheeling

open access: yes, 1994
A new class of pulsewidth-modulated zero-voltage-switching multi-resonant converters (PWM-ZVS-MRCs) is presented. Instead of controlling the switching frequency, the output voltage is regulated by controlling the freewheeling period of the resonant ...
