Comparison of cuk and buck converter fed electronically commuted motor drive

In this paper novel technique of Controlling electronically commutated motor drive (PMBLDCMD) using cuk converter explain. A DC-DC converter topology is employed for speed control BLDC MOTOR and operated with voltage follower Approach in discontinuous conduction mode (DCM). This paper give comparative performance of speed controlling of BLDC motor using Buck and cuk converter. The performance of BLDC motor is studied using MATLAB Simulation for wide range of speed control.
