Abstract

Modulation methods for AC-to-AC pulse-modulated series-resonant power converters are analyzed. A novel control approach based on space vector dynamical equations is proposed. The obtained equations prescribe the dynamics of the complete power converter including filters. The derived modulator can overcome the drawbacks of pulse modulation techniques. The sliding mode control is considered to control the power factor of the pulse-modulated power converter. The suggested modulation mechanism and philosophy are generally applicable for the entire class of the pulse-modulated soft-switching power converters
