This paper aims to compare the performance of two control schemes viz. hard switched and phase shifted control scheme for full bridge DC-DC converter used in photovoltaic application .The proposed converters are designed for 650W photovoltaic input power. Voltage and current waveforms at various test points like across IGBT, transformer primary and secondary, output etc. are compared and results are presented. From results it can be seen that in phase shift control simultaneous transition of voltage across IGBT and current through IGBT is avoided hence reduction in switching losses , dv/dt, di/dt effects and EMI effects can be achieved. At higher switching frequencies phase shift control scheme is meritorious over hard switched control scheme.
