Abstract :
This paper presents a innovative prototype of PWM soft-switching DC-DC forward type converter designed for specific low voltage large current condition at 24 V battery input. To achieve soft-switching, prototype of ZCS PWM DC-DC forward type converter applies additional control mode at partial operating area. The proposed converter is controlled by dual modulation as PWM-PDM at low duty operation. The soft-switching forward converter controlled PWM-PDM dual control scheme which can efficiency operate over wide load ranges under conditions of ZCS and active voltage clamped switching is established.
