In transformer-less grid connected solar PV system, the step-up dc-dc converter plays a crucial role to boosted up the DC-link voltage to desired value. This brief proposes a single switch hybrid (switched capacitor and inductor) network (SSHN) based step-up dc-dc converter to meet DC-link voltage. Compared to recently reported converters, the proposed SSHN dc-dc converter can achieve large voltage gain with minimum number of power devices. Due to presence of passive components in the hybrid network, it has fewer ripple content in the voltage and current, which helps to neutralize the interferences and prolongs the life of the power devices. The detailed operating waveform and analysis under various conduction modes have been presented in this brief. Moreover, the comparative performances of the proposed converter are discussed in detail. Finally, to validate the operational details a 500 W experimental prototype was built and the results are presented in this brief. It is worthy to note that the proposed SSHN converter can yield the maximum experimental efficiency of 94.3% at 300 W.
