A rectifier is a device that converts alternating current (AC) to direct current (DC). It is done by using a diode or a group of diodes. Half wave rectifiers use one diode, while a full wave rectifieruses multiple diodes. The working of a half wave rectifier takes advantage of the fact that diodes only allow currentto flow in one direction.
A half wave rectifier is the simplest form of rectifier available. We will look at a complete half wave rectifier circuit later – but let’s first understand exactly what this type of rectifier is doing. The diagram below illustrates the basic principle of a half-wave rectifier. When a standard AC waveform is passed through a half-wave rectifier, on...
The output waveform we have obtained from the theory above is a pulsating DC waveform. This is what is obtained when using a half wave rectifier without a filter. Filters are components used to convert (smoothen) pulsating DC waveforms into constant DC waveforms. They achieve this by suppressing the DC ripples in the waveform. Although half-wave re...
We will now derive the various formulas for a half wave rectifier based on the preceding theory and graphs above.
Half wave rectifiers are not as commonly used as full-wave rectifiers. Despite this, they still have some uses: 1. For rectification applications 2. For signal demodulation applications 3. For signal peak applications
The main advantage of half-wave rectifiers is in their simplicity. As they don’t require as many components, they are simpler and cheaper to setup and construct. As such, the main advantages of half-wave rectifiers are: 1. Simple (lower number of components) 2. Cheaper up front cost (as their is less equipment. Although there is a higher cost over ...
The disadvantages of half-wave rectifiers are: 1. They only allow a half-cycle through per sinewave, and the other half-cycle is wasted. This leads to power loss. 2. They produces a low output voltage. 3. The output current we obtain is not purely DC, and it still contains a lot of ripple (i.e. it has a high ripple factor)
All of the theory above has dealt with a single phase half wave rectifier. Although the principle of a 3 phase half wave rectifier is the same, the characteristics are different. The waveform, ripple factor, efficiency, and RMS output values are not the same. The three-phase half wave rectifier is used for the conversion of three phaseAC power to D...
