Soft Computing Technique for Double Boost Converter Fed PMDC Drive

This paper deals with the Implementation of high speed and high power Separately excited PMDC motor fed from Double boost converter. In many industries , the PMDC motor plays a vital role for variety of control applications. The speed and output power are the notable parameters in variety of low voltage applications. The PMDC motor Drives are usually meant for constant speed applications. Generally, in most of the power electronics application, the voltages fed to the converter at input was being wasted more in the form of switching losses. Hence the efficiency of the driving system was reduced considerably. The aim of this work is to improve the efficiency of the PMDC drive by implementing double boost converter by reducing the switching losses considerably. Simulation result proves the effectiveness of the proposed PMDC Drive fed by Double boost converter by improved speed response and output power compared with Bridgeless boost converter fed PMDC Drive.
