Impact of Half-Wave Uncontrolled Rectification on DC Motor Performance

Abstract

Half-wave uncontrolled rectifiers play a pivotal role in converting sinusoidal alternating current (AC) signals into direct current (DC) voltage. This study examines the impact of a single-phase half-wave uncontrolled rectifier on the performance dynamics of a DC motor, particularly focusing on the relationship between rotational speed (RPM) and time. Utilizing a diode as both a rectifying element and a circuit switch, the rectifier introduces significant variations in the motor's operational characteristics. Experimental results demonstrate that the RPM of the DC motor exhibits a proportional increase with time under specific rectification conditions, shedding light on the transient behavior and stability of the system. This research contributes to the understanding of how rectification methods influence motor performance, offering valuable insights for optimizing motor control in industrial and engineering applications. The findings also pave the way for future advancements in efficient rectifier designs and motor performance analysis.
