Performance Analysis of a Single-Phase Half-Wave Uncontrolled Rectifier on Lamp Flicker

Abstract

An uncontrolled rectifier is an electrical circuit designed to convert sinusoidal waveforms from an alternating current (AC) voltage source into direct current (DC) voltage. The single-phase half-wave uncontrolled rectifier utilizes a diode as both the rectifying component and the circuit switch. This type of rectifier significantly impacts the performance of lighting systems, particularly the flickering behavior of light-emitting diode (LED) lamps within electrical circuits. This study evaluates the rectifier's influence on lamp flicker characteristics under varying operational conditions, focusing on its effectiveness in improving lighting stability and identifying potential drawbacks such as harmonic distortions. The findings aim to contribute to the development of enhanced rectifier designs tailored to modern engineering applications in power electronics and sustainable lighting systems.
