Closed Loop Control of the Two Switch Serial Input Interleaved Forward Converter Fed DC Drive

Abstract

This paper deals with closed loop control of the two switch Interleaved Forward Converter with motor load. When any sudden change occurs at the input of the open loop two switch interleaved forward converter, the output is disturbed for a long time. In order to avoid this, a closed looped control is introduced.  By using closed loop control, the steady state error in speed is reduced. The DC input is converted into high frequency AC using the Forward Converter. The AC is rectified using a Half-wave rectifier. The output voltage is regulated using the closed loop system. The simulation results are compared with the theoretical results.
