This paper presents detailed analysis and operation of Asymmetric Half Bridge (AHB) converter topology, shared switch converter, and Miller topology for 4- phase Switched Reluctance Motor (SRM) drives. The control strategy implemented in this study involves the application of PI (Proportional Integral) Speed control with PWM switching method for each topology. By employing this control strategy, the system aims to regulate the speed of the motor and achieve desired performance while ensuring efficient power utilization. The PI controller is utilized to adjust the motor's speed based on the error between the desired and actual speeds, enabling precise control. Additionally, the PWM (Pulse with Modulation) switching method is employed to modulate the motor voltage, allowing for smooth and continuous speed adjustments. This combination of control techniques offers a comprehensive approach to optimize the performance of each topology and enhance the overall system efficiency. Simulation and Experiment results show that AHB and Shared Switch have better performance than Miller. But Miller converter needs the least number of Switching components. Although the performance of Shared Switch is equal to AHB, this topology only can be applied for SRMs with even number of phases. The simulation and experiments results are based on MATLAB/SIMULINK and TMS320F28379D.
