This paper is used to design a rugged and low-cost drive, supplied by a battery, using a BLDC motor. The DSP processor is very powerful, compact and multi-functional, containing many inbuilt modules like the Analog-to-Digital converter. The rotor position is sensed by means of Hall position sensors. The CUK converter has advantage of this topology is a continuous current at both the input and the output of the converter and reduces the switching losses and current harmonics. The PWM pulses for each phase are generated by the DSP and are given to the MOSFET driver. The complete system model is simulated in MATLAB/ Simulink environment. Hardware implementation for the speed control has been achieved by DSP controller TMS320C243. The ideal topology for commercial applications that are supplied from the utility.
