Abstract :
Soft switching resonant power converters utilize pulse frequency modulation techniques in order to synthesize a low frequency behaviour. In this paper, pulse modulation techniques are analyzed. A novel control approach based on space vector dynamical equation is suggested. The obtained equations prescribe the dynamics of the entire converter including the filters. A modulator designed on their bases can solve the drawbacks of pulse modulation techniques. A sliding mode control is considered in order to control the power factor of the pulse modulated converter
