Abstract:
Dynamic response of a converter plays an important role in many applications which change load in a rapid manner, especially in PoL(Point of load)applications. Here a new method for improving the dynamic response of a converter is presented. Here separate control schemes are implemented 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. Simulation model is done in Matlab/Simulink 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
