Abstract :
A new zero-voltage-switching multiresonant boost convertor operating at constant switching frequency is presented. Its output voltage is regulated by controlling the freewheeling period of the resonant inductor. It possesses the advantages of a PWM convertor and frequency-modulated multiresonant convertor. Moreover, by absorbing all major parasitic components in its resonant circuit, parasitic ringing is eliminated.
