A new phase-controlled resonant inverter is obtained by paralleling the ac loads of two identical parallel resonant inverters. A phase shift between the drive signals of the two inverters controls the amplitude of the output voltage of the new inverter. A voltage-driven rectifier is used as an ac load of the inverter which results in a phase-controlled parallel resonant dc-dc converter. A frequ...

Resonant converters are included in a wide range of converters. The strategy of using one is to design a highly efficient converter while eliminating a common disadvantage of traditional implementations based on Pulse-Width Modulation (PWM) – high switching losses. Many different solutions have been suggested, implemented, and tested in recent years, and many of them are now widely used in comm...
