Abstract :
This paper proposes a digital control system based on ARM micro processor LPC2214, analyses this control systempsilas structure and realization, and introduces a practical full bridge phase-shift ZVZCS PWM converter topology. Theory analysisses and experiments have showed that this PWM full bridge converter based on the digital control can realize ZVS of the leading-legs and ZCS of the lagging-legs in the whole range of load. It has a lower loss and cost , but a better prospect.
