of a single-phase half-controlled converter, a critical component in power electronics, often used in applications such as DC motor control, battery charging, and power supply systems. The study examines the operation of the converter with various load types, including resistive (R), resistiveinductive (RL), and resistive-inductive capacitive (RLC) loads. The converter circuit utilizes a combination of thyristors and diodes to achieve controlled rectification and freewheeling actions. Key observations include the analysis of output voltage and current waveforms under different firing angles, demonstrating the impact of load and firing delay on performance. Through theoretical discussion, numerical problem-solving, and practical waveform observations, the project highlights the efficiency and operational characteristics of the single-phase half-controlled converter. Safety precautions and procedural guidelines ensure accurate data collection and a safe working environment. This study aims to deepen understanding of controlled rectification techniques and their implications in practical scenarios

1.INTRODUCTION A single-phase half-controlled converter is a vital component in power electronics that converts AC power into DC power. It uses a combination of thyristors and diodes to regulate the output voltage and current. The controlled nature of the converter allows it to adjust the DC output by varying the firing angle of the thyristors. This type of converter is extensively used in various industries due to its simplicity, reliability, and cost-effectiveness. Efficient AC-DC converters are essential in applications where variable voltage and current are required. With the increasing demand for energy-efficient systems, there is a need for converters that
