Design an Efficient Cuk Converter for a BLDC Motor Drive

In this research work, designing of Cuk converter which operated in a closed loop using PI controller technique to maintain the respective reference voltage has been carried out. The regulated voltage obtained at the DC link capacitor terminals is then provided to the voltage source inverter (VSI) in order to feed the load. The Cuk converter generated inverting output. A BLDC motor is considered as a load in this research work. The Cuk is a type of DC-to-DC converter that either increases or decreases the output voltage according to our needs. In addition, Cuk converter provides advantages like high efficiency, having simple configuration, not having any transformer hence low losses, operates on high frequency and easy control strategy. In this paper, the performance of BLDC motor is analyses on the basis of its transient performance, steady state performance and dynamic performance. These results are generated using MATLAB/Simulink.
