A Novel Dc-Dc Converter With ZVS, ZCS Switching Based Grid Connected Photo Voltaic Inverters
In this venture a single –phase step step-up converter is suggested, designed not only to boost the relatively low
photovoltaic or pv (PV) voltage to a higher bus voltage with best quality, but also to offer a neutral factor based half-bridge-
based inverters. As a result, the low volts –rated power devices can be involved to reduce the transmission failures. All these
factors advance the circuit efficiency in the great step-up applications, especially for the half-bridge based PV inverter
systems. The leading efficiency of the system is 96.5% and the efficiency is over 94% in a wide load range.
