Abstract

Significant improvements of the DC-DC converters create the straightforward method to control the speed of the DC motor. One of the important DC motors is the Brushless DC motor which is utilized in various electrical fields. This paper focuses on the control at different speeds for a Brushless DC motor. In order to make the proper voltage to run the motor, two DC-DC converters (Boost and Buck) are tested using two different switches (GaN and SiC transistors). After making the Simulink model and connecting to dSPACE to send the suitable pulse to the transistor of the converter, the DC motor starts working by applying the DC voltage to the converter. This process includes modeling in MATLAB Simulink, dSPACE, and an experimental setup to run the DC motor. Furthermore, the performance of GaN and SiC switches in Boost and Buck converters are compared to each other in this project in terms of output parameters, efficiency, and providing the accurate speed for DC motor.
