Abstract :
This paper proposes a soft-single-switched forward converter with low current and voltage stresses and two derived converters. These converters operate with a nondissipative snubber in ZCS mode at turning on and ZVS mode at turning off. The output voltage is controlled by using PWM technique. It is carried out a detailed study, where operating principles and some simulation and experimental results are presented.
