Abstract

The double modulation power converter (DMC) is able to modulate both the amplitude and the duty cycle. Zero voltage switching is achieved at the same time. Constant switching frequency, simple control and easy-to-design gate drive circuit make the DMC an ideal power converter to fill the low to medium power application gap in which the soft switching phase modulation method is costly to apply. Experimental results show that the DMC is practical to use
