A Design Procedure and Control Method for Improving Efficiency of a Family of Resonant Converters Over Wide Operating Conditions by Jasem Shahsevani, Reza Beiranvand

“…However, low efficiency under light-load or no-load conditions is one of their main challenges, which arises when their switching frequencies deviate significantly from their resonance frequencies during output voltage regulation, resulting in high circulating currents and switching harmonics values. Here, a novel design procedure and control method are proposed for the resonant converters, which have parallel components in their resonant tank circuits to address their light-load or no-load low-efficiency issues. …”
