Novel Soft Switching PWM Converter Using A New Parallel Resonant DC-Link

A novel soft switching PWM converter for high frequency ACIDC andlor DCIAC power conversion is presented by using a new parallel resonant dc-link(PRDCL) and by adopting single phase soft switching(SPSS) technique. The new PRDCL provides variable link pulse position as well as variable link pulse ,width. which is quite different feature from the other resonant dc-links and thus the PWM capabilit...

Steady-state modeling of a phase-shift PWM parallel resonant converter

Purpose – To derive an analytical model for a dc-ac-dc parallel resonant converter operating in lagging power factor mode based on the steady-state operation conditions and considering the effects of a high-frequency transformer. Design/methodology/approach – A range of published works relevant to dc-ac-dc converters and their control methods based on pulse-width-modulation technique are evalua...

Robust Controller Design for a Parallel Resonant Converter Using -Synthesis

DC-to-dc resonant converters have been the object of much attention lately. These converters have the potential to provide high-performance conversion without some of the problems associated with classical pulse-width modulation (PWM)-based converters, thus allowing for smaller, lighter power supplies. However, in order to achieve this, a suitable control circuit, capable of maintaining the des...

A new phase-controlled parallel resonant converter

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...
