Three level buck converter with improved dynamic performance using linear-non linear control

Abstract: Dynamic response of a converter plays an important role in many applications which change load in a rapid manner, especially in Po L(Po int of load)applicat ions. Here a new method for imp roving the dynamic response of a converter is presented. Here separate control schemes are imp lemented during steady state as well as transient load conditions. A three level buck converter topology with fast transient response is discussed here. This topology does not require a soft start up circuitry for three level buck converter. Simu lation model is done in Matlab/Simu lin k and the result shows a great improvement in dynamic response of the system.

Keywords: Three level buck converter, dynamic response, transient response, soft start up.
