Analysis of Output Voltage Characteristics in a Single-Phase Half-Wave Controlled Rectifier Circuit for DC Motor

Abstract

A DC Electric Motor, also known as a Direct Current Motor, is a device that converts electrical energy into kinetic energy or motion. DC motors operate with two terminals and require direct current (DC) to function. These motors are widely utilized in electronic and electrical applications that rely on DC power sources, such as vibrators, DC fans, and electric drills. One of the key parameters for controlling the performance of a DC motor is its rotational speed, which is commonly measured in revolutions per minute (RPM). This speed can be adjusted to meet the requirements of various applications. To achieve variable speed control, a rectifier circuit is often employed. Specifically, a single-phase controlled rectifier circuit is used to convert alternating current (AC) from the power grid (typically 220V AC) into direct current (DC). The controlled rectifier circuit plays a crucial role in rectifying the input AC voltage and providing a stable and regulated DC output to drive the motor, ensuring optimal performance. This paper explores the output voltage characteristics of the single-phase half-wave controlled rectifier circuit and its impact on the performance of a DC motor. The study focuses on the design and analysis of the rectifier circuit, aiming to improve efficiency, stability, and motor control..
