In addition, the input rectifier acts The MOSFET is an important element in embedded system design which is used to control the loads as per the requirement. A rectifier is an electronic device that changes alternating current into direct current. A rectifier helps in converting a pulsating alternating current to direct current, which flows only in one direction. This process is called rectification. All these three rectifiers have a common aim that is to convert Alternating Current (AC) into Direct Current (DC) . The half-wave rectifier converts or rectifies only half cycle of input waveform. [15] The modern electrolytic capacitor , an essential component of most rectifier circuit configurations was also developed from the electrolytic rectifier.

Types of Full Wave Rectifier The full-wave rectifier can be designed by using with a minimum of two basic diodes or it can use four diodes based on the topology suggested. Half Wave Rectifier; Full wave Rectifier; Half wave rectifier only converts half of the AC wave into DC signal whereas Full wave rectifier converts complete AC signal into DC. The type of rectifier which is used to rectify only the half cycle of the input AC waveform is called half wave rectifier. 9.3 Single phase uncontrolled half wave rectifier This is the simplest and probably the most widely used rectifier circuit albeit at relatively small power levels. Similar to the uncontrolled rectifier types, these thyristor based converters are also classified into following types. A rectifier is an electrical device construct of one or more diodes that allow the flow of current only in one direction. 5, the rectification occurs during the whole period of the voltage. The DC voltage on the load is the average over the period T of the output voltage of the rectifier: DC L 0 1 ()d T Vvtt T = ³. Simply defined, rectification is the These are mainly P-N junction diodes, Photosensitive diodes, Zener diodes, Schottky diodes, Varactor diodes. Fig. Full wave rectifier with the diagram Generally rectifier is classified into two categories. In a large number of electronic circuits, we require DC voltage for operation. 1.4V is used up in a bridge rectifier because there is 0.7V across each diode when conducting and there are always two diodes conducting, as shown in the diagram. As it is clear from the A/C wave diagram, that AC contain two cycles, positive cycle and negative cycle. Types of Full Wave Rectifier. We know that the core use of rectifier is to convert AC current into DC current. Half Wave Rectifier The process of removing one-half of the input signal to establish a dc level is called half-wave rectification. In silicon diode, the dark band indicates the cathode terminal and the other terminal is anode. Selenium rectifier consists of a layer of alloy and a layer of selenium on a steel plate as shown in Fig. There are two main types of full-wave rectifiers, and they are: Two diodes full-wave rectifier circuit (requires a center-tapped transformer and is used in vacuum tubes) Bridge rectifier circuit (doesn’t require a centre-tapped transformer and is used along with transformers for efficient usage) Advantages of Full Wave Rectifier The figure below shows the full-wave rectification of three-phase AC used for supply...
