e main advantage of resonant technique is reduction of switching losses via mechanisms known
as zero current switching (ZCS) and zero voltage switching (ZVS). e switch-on and/or switch-o
converter semiconductor components can occur only at zero crossing of the resonant quasi-sinusoi-
dal waveforms. is eliminates some of the switching loss mechanisms. Hence, switching losses are
reduced, and resonant converters can operate at switching frequencies that are considerably higher
than in comparable pulse width modulation (PWM) hard switching converters. ZVS can also eliminate
or reduce some of the ele ...
