Abstract :
A technique for realizing pulse width modulation (PWM) capability in resonant DC link converters is presented. This technique eliminates the subharmonics present in the conventional discrete pulse modulated converters without requiring any additional switching devices. Detailed design-oriented analysis enumerating the tradeoffs involved are presented. Control techniques for simultaneously accomplishing link and output control are considered. Simulation results verifying the principle of operation are presented and backed up by experiments
