Abstract :
This paper presents 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 techniques. A detailed theoretical study, where operating principles and some simulation and experimental results are presented, is carried out
