Abstract :
Soft switching resonant 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 the space vector dynamical equation is suggested. The obtained equations prescribe the dynamics of the entire converter including the filters. The modulator designed on their base can solve drawbacks of pulse modulation techniques. The sliding mode control is considered in order to control the power factor of the pulse modulated converter
