Abstract

Photovoltaic, wind, and fuel-cell energy are the front-runner renewable- and alternate-energy solutions to address and alleviate the imminent and critical problems of existing fossil fuel-energy systems. There will be severe voltage spikes and ringing across the switches during turnoff. They are caused by the transformer and other parasitic leakage inductances combined with a very high current reverse going through the transformer primary side. A key aspect of ...
