Rectifiers
Rectifiers are electrical devices that convert current from alternation to direct mode. The process of conversion is called rectification which is the opposite of the process of inverting current from direct to alternating. The rectifiers are being used as detectors of radio signals and components of power supplies. A rectifier may be made of mercury arc valves, vacuum tube diodes, solid state diodes and other materials. There are various ways on connecting diodes to enable a rectifier in converting alternating current to direct current.
A bridge rectifier is the most important among the ways of connecting diodes in the process of rectification since it produces varying full wave rectifier for direct current. Furthermore, a full wave rectifier can be made from two diodes once a center tap transformer is used but this method is rarely used since diodes are cheaper. Nowadays, the plating rectifiers are able to convert alternating current to direct current with the use of semiconductors that can only conduct current for one direction wherein the output can be either positive or negative.
The process of silicon controlled rectifier consists of a four-layer solid state device that controls the current flow. The acronym of SCR or silicon-controlled rectifier is GE’s (General Electric) trade name for a thyristor type. It was developed by a team of engineers that was led by Gordon Hall and was even commercialized in 1957 by Frank W. Bill. Additionally, a silicon controlled rectifier can be a conventional rectifier that can be controlled by a signal from logic gate. On the other hand, there is a time constant for half wave rectifier since it uses a silicon controlled rectifier or the SCR.
The high voltage rectifiers only work along with high voltage capacitor in effectively doubling the current high voltage that is supplied by the power transformer. This powerful voltage in the process of high voltage rectifier is being applied on the magnetron tube, which causes the supply of energy. Selenium rectifier has higher reverse voltage rating of 20 to 30 volts than any process of rectifiers since selenium has a higher forward current resistance than copper oxide.
