A New Cubic Transformerless Converter For Applying in Renewable Applications

Abstract

A new non-isolated cubic converter has been suggested for applying in renewable systems due to the high voltage gain and continuous input current. Moreover, the low stress on the semiconductors is an other benefit which decreases the losses. The base of the topology is a combination of two Boost converters and a Buck-Boost converter which two capacitors are series in the output terminal. The mathematical calculations have been done in CCM. Two comparisons have been done which are for non-ideal voltage gain and the structural features of the proposed converter and some new suggested converters. The maximum voltage gain has been achieved to 22 for the 160 W output power and 50 percent duty cycle. The simulation results have been obtained by PLECS and illustrated.
