Photovoltaic(PV) residential power system is an importantapplication of renewable energy. In this manuscript
a tale soft-switching current fed push-pull front end converter based I nverter is offered. push-pull converter has only
two primary device with common ground to supply and result-in Straight forward and summary the gattingrequirement.
The device voltage is clamped naturally by secondary modulation without active clamping circuit or passive snubber.
zero current switching(ZCS) Of primary device and zero voltage switching (ZVS) of secondary device is achieved. Soft
switching is inherent remaining to anticipated secondary modulation load independent, and is maintained during wide
variation of input voltage and power transfer capacity and suitable for PV application.
