Abstract Enhance the efficiency of the motor drive by Power Factor Correction (PFC) play a critical part in the energy saving during energy consumption. Permanent magnet brushless DC Motor (PMBLDCM) drives are being utilized in numerous variable speed applications because of their high productivity, quiet operation, high reliability, simplicity of control, and low maintenance requirement. These drives have power quality issues and poor power factor at input AC mains as they are mostly fed through diode bridge rectifier. To overcome such issues a single stage single-switch power factor correction AC-DC converter topology are utilized. This paper gives the relative evaluation of the different converter with Proportional Integral Controller (PIC) And Fuzzy Logic Controller (FLC). In this system, the speed of the motor is shifted by the Impedance Source Inverter (ZSI) dc voltage. The proposed drive is realized to achieve a unity power factor at ac mains for a broad scope of speed control and supply voltage flucation. A MATLAB/Simulink environment is used to reproduce the model to fulfill an extensive variety of speed control with improved Power Quality (PQ) at the supply.
