Abstract

The objective of the paper is to develop a solar based soft switching isolated DC–DC converter for battery charging applications. The use of conventional boost converter is likely to decrease the efficiency because of hard switching, which generates loss during the switch on/off. But soft switching technique informs well with zero-current switching by the resonant inductor at turn-on, and zero-voltage switching by the resonant capacitor at turn-off. The major drawback of switched mode power converter operation is to produce EMI due to large dv/dt and di/dt during the time of switch mode operation. Therefore, to realize high switching frequencies in converters, the switching losses and EMI emission are reduced if each controlled switch in the converter is turn-on or turn-off only when current passing through and or voltage across the switch is zero. The FPGA (Field Programmable Gate Array) controlled DC–DC converter is used to provide zero voltage and zero current switching of all the main power devices. In this paper, the gate pulses are generated from FPGA (Field Programmable Gate Array) controller. This paper also describes the main operational modes of the converter as well as its simulation and Hardware results.
