Pulse charger with zero current switching and isolation for electric vehicles and renewable energy applications

Abstract

Fast charging has become a major concern due to advents of more convenient methodologies of extracting renewable energy with the aid of new technology. Batteries are used widely to store energy and a charging technique that hinders the chemical reactions impeding the current is found. This technique known as pulse charging is thus comparatively fast and has received extensive attention over the last decade. Simultaneously, many fast charging topologies have been developed over the years with their own strengths and weaknesses. In this research a novel pulse charging topology with soft switching and isolation is introduced which facilitates high power pulse charging due to reduced switching losses.
