Abstract

This paper explained about switching losses in prescribed circuit. Batteries are the primary energy-storage devices in ground vehicles. Now-a-days battery fed electric drives are commonly being used for electric vehicles Applications, due to various advantages, such as nearly zero emission, guaranteed load levelling, good transient operation and energy recovery during braking operation. To full fill these requirements converters with bidirectional power flow capabilities are required To connect the accumulator (battery) to the dc link of the motor drive system .In the present work closed loop operation of bi directional dc-dc converter feeding a dc series motor. Bi-directional dc-dc converter having some switching Losses. so we have to reduce these switching losses by using Soft switching technique .The confirmation of circuits operation and waveforms, measurement of conversion efficiency, and loss analysis are verified using of MATLAB.
