Abstract

In this paper, the novel circuit topology of half-bridge soft switching PWM DC-DC power converter with a high frequency planar transformer link was presented. The operating principle and switching pattern of the half-bridge soft switching PWM DC-DC power converter described for 40 kHz, 36V and 400A output were illustrated and discussed for low voltage and large current output applications such as telecommunication and automotive applications. The power loss analysis of the proposed soft switching DC-DC power converter was discussed and evaluated as compared with hard switching PWM DC-DC power converter with a high frequency link. The practical effectiveness of the proposed DC-DC power converter operation under soft switching PWM scheme was actually proved from a practical point of view and the high efficiency and power density of this converter could be achieved on the basis of experimental results for low voltage and large current power supplies.
