Full-Wave Rectification and Half-Wave Rectification

A rectifier is an electrical device that converts alternating current AC , which periodically reverses direction, to direct current DC , which flows in only one direction. The reverse operation is performed by the inverter. The process is known as rectification , since it "straightens" the direction of current. Physically, rectifiers take a number of forms, including vacuum tube diodes , wet chemical cells, mercury-arc valves , stacks of copper and selenium oxide plates, semiconductor diodes , silicon-controlled rectifiers and other silicon-based semiconductor switches. Historically, even synchronous electromechanical switches and motors have been used. Early radio receivers, called crystal radios , used a " cat's whisker " of fine wire pressing on a crystal of galena lead sulfide to serve as a point-contact rectifier or "crystal detector". Rectifiers have many uses, but are often found serving as components of DC power supplies and high-voltage direct current power transmission systems.

The basic half-wave rectifier circuit and the input and output waveforms are shown in the, diagram. Rectifiers are of two types: half-wave rectifiers and full-wave rectifiers. Since the It utilizes only half of AC cycle for the conversion process. Rectifier Efficiency This shows that the half wave rectifier without a filter is relatively a poor device for converting AC into DC. The half wave diode rectifier is used in a variety of ways and in a host of different types of circuit.

Printed Half-Wave and Full-Wave Rectifier Circuits Based on Organic Diodes Abstract: Presently, most circuits fabricated using organic materials and printing methods have been adopted directly from solid-state inorganic electronics. However, the characteristics of organic electronic devices can differ remarkably from their inorganic equivalents, and therefore, the performance assumptions made about inorganic devices may not be applicable in organic electronics. In this paper, we report a printed diode-based half-wave rectifier having high yield, good air stability, and 3. Due to the high yield and good performance of the individual diodes, fabrication of more complex devices is possible.

In both cases, rectification is performed by utilizing the characteristic that current flows only in the positive direction in a diode. Full-wave rectification rectifies the negative component of the input voltage to a positive voltage, then converts it into DC pulse current utilizing a diode bridge configuration. In contrast, half-wave rectification removes just the negative voltage component using a single diode before converting to DC. From this, it can be said that full-wave rectification is a more efficient method than half-wave rectification since the entire waveform is used. Also, a ripple voltage that appears after smoothing will vary depending on the capacitance of this capacitor and the load. Given the same capacitance and load, ripple voltage is smaller with full-wave rectification than haif-wave rectification.

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. While Full-wave Rectifier, is bi-directional, it conducts for positive half as well as negative half of the cycle. Thus, it is termed as full wave rectifier.

To understand the effect of a reservoir capacitor upon the rectified waveform and its mean value. Half wave rectifier has around 0. Design the circuit diagram.
