Reduced Switch Inductor DC-DC Converter with Increased Gain for PV System

A Reduced Switch Inductor High Gain Dc-Dc Converter RSI-HGDC for PV system is provided in this paper. This converter comprises of a reduced switch inductor dc to dc converter with inductor circuit, which decreases the voltage stress and enhance voltage gain of the main switch. Reduced number of switches are employed in this proposed converter, which enhances the efficiency and decreases the switching losses of the converter. In order to maintain the output voltage regulation and runs the converter within its safe limits an MPPT control algorithm is described. The proposed converter may also achieve a low input current ripple, high voltage gains and high efficiency for a broad variety of applications including PV systems that need minimal number of components and high voltage gains. The results of the designed converter are examined by simulation as well as in experiment.
