Electrical Academia. A rectifier is a device to convert AC electricity to DC. Except for batteries that are small sources of DC electricity, or the rechargeable ones that store electricity, most of the domestic devices that work with DC electricity use rectifiers. At the industrial level, there are industries that need DC electricity to run DC motors or processes that can function only with DC; they either must have their own generators or must obtain their DC requirement from AC sources by rectifiers. Both single-phase and three-phase AC can be converted to DC.
A simple Half Wave Rectifier is nothing more than a single pn junction diode connected in series to the load resistor. As you know a diode is to electric current like a one-way valve is to water, it allows electric current to flow in only one direction. This property of the diode is very useful in creating simple rectifiers which are used to convert AC to DC. If you look at the above diagram, we are giving an alternating current as input. The output voltage is measured across load resistor RL.
Rectifiers are mainly classified into three types namely half-wave, full-wave, and bridge rectifier. The main function of all these rectifiers is the same as the conversion of current but they not efficiently convert the current from AC to DC. The center tapped full wave rectifier as well as bridge rectifier converts efficiently. A bridge rectifier circuit is a common part of the electronic power supplies. Many electronic circuits require a rectified DC power supply for powering the various electronic basic components from available AC mains supply.
FIg Half wave rectifier using one diode. The output DC voltage of a half wave rectifier, given a sinusoidal input, can be calculated with the following ideal equations: Full-wave rectification: A full-wave rectifier converts both the positive and negative halves of the input waveform to a single polarity positive or negative at its output. In this lecture, problems of half wave rectifiers have been solved. Course Overview and Introduction to Rectifiers.
Peak inverse voltage PIV Peak inverse voltage or peak reverse voltage is the maximum voltage a diode can withstand in the reverse bias condition. The rectifier efficiency of a full-wave rectifier is A full wave rectifier produces positive half cycles at the output for both half cycles of the input. Ic repeats once a cycle for half wave and twice a cycle for full wave, Figure 2 shows roughly how this looks in the full-wave case, both volt- age across C1 and the successive current waves through Two diodes are so connected across the terminals of center tapped transformer secondary terminals that one diode conducts for positive half cycle and another diode conduct for negative half cycle of the supply input. Draw the input waveform, V i, and the output waveform, V o 4.
It utilizes only half of AC cycle for the conversion process. The Half-Wave Rectifier is unidirectional; it means it will allow the conduction in one direction only. This is the reason that it is called Half Wave Rectifier.
