Abstract


Because boost converter circuits allow for precise speed regulation, frequent starting, flexible speed control, and support for stopping and reversing operations, they are becoming more and more common in industrial and electrical systems for powering DC motors. However, because these converters are made of non-linear devices, they introduced harmonic distortions that lowered the system's power quality and decreased the performance of the DC motor that was connected to them. This paper presents a low-cost and effective boost chopper circuit that drives a separately excited DC motor by combining it with an RC filter. Matlab/Simulink was used to simulate an RC filter model based on a boost converter that has a 120 V input DC voltage, a 50% duty ratio, and a 50 kHz switching frequency. The separately excited DC motor is powered by the boost converter's average output voltage and current. The RC filter significantly reduced total harmonic distortion (THD) from 37% to 11.8%. In addition to harmonic mitigation, this study investigated the efficiency of a separately excited DC motor, and a significant improvement in the motor’s efficiency from 74.42% without the filter to 91.42% with it was observed. This research underscores the effectiveness of integrating an RC filter with a boost chopper circuit to enhance power quality and optimize the performance of a DC motor system.
