RECTIFIERS ABSTRACT A rectifier is an electrical device that converts alternating current (AC) to direct current (DC) and the process is known as rectification. Rectifiers have many uses including as components of power supplies and as detectors of radio signals. Rectifiers may be made of solid state diodes‚ vacuum tube diodes‚ mercury arc valves‚ and other components. When only one diode is used to rectify AC (by blocking the negative or positive portion of the waveform)‚ the difference between

INTRODUCTION A full wave rectifier is a device which is used to rectify all the alternating current components in an alternating supply and make it purely a direct current. The two alternating halves of an alternation current are rectified in a full wave rectifier which is an advantage over a half wave rectifier. Most of electronic devices cannot withstand very high voltage or alternating current due to its intense high power. The use of batteries in all devices is not practical as their replacement

This controller has been verified via simulation in Simulink using a continuous time plant model and a discrete time controller. Index Terms—power‚ factor‚ correction‚ boost‚ rectifier. I. INTRODUCTION. Single-phase power factor correction (PFC) circuits provide rectification of the line voltage to a regulated dc voltage while shaping the input current to be a sinusoid and in phase with the line voltage [1]. Often‚ the PFC acts

7. Tuning Let us examine each of these applications with some considerable detail. RECTIFICATION: The process of converting AC into DC is called rectification. Diodes can be used as half wave rectifiers and full wave rectifiers. Half Wave Rectifier: Circuit Diagram: . In the Half wave rectifier circuit shown above the transformer serves two purposes. 1. It can be used to obtain the desired level of dc voltage (using step up or step down transformers). 2. It provides isolation from the
