Summary: 
Voltage resonant converters with multiple resonant switches operating at fixed switching frequency are presented. Resonant switches are connected in parallel so that the power conditioning is achieved by the phase-shift modulation method instead of the switching frequency modulation method. Switching losses are predicted to be very small due to it's zero-voltage switching. Steady state characteristics of the proposed converter are analyzed, and the analytical results are verified by experiments.
