By switching on and off, theoretically a silicon-controlled rectifier dimmer does not heat up (efficiency close to 1.0).

Such high frequencies are not feasible with inexpensive power semiconductors; in 1973 the silicon-controlled rectifiers used were limited to no more than 40 kHz.

The TO-3 metal can package is commonly used for power transistors, silicon-controlled rectifiers, and, occasionally, integrated circuits.

Some sources define silicon-controlled rectifier (SCR) and thyristor as synonymous.

This psychedelic lighting was made economical by the development of the silicon-controlled rectifier (SCR).

While still at high school, he entered a science fair for which he built a silicon-controlled rectifier, a device that can be used to control alternating current.

Solid-state relays control power circuits with no moving parts, instead using a semiconductor device to perform switching-often a silicon-controlled rectifier or triac.

Silicon-controlled rectifier (SCR)

The sensor can be a photoresistor, a photodiode, a phototransistor, a silicon-controlled rectifier (SCR) or a triac.

The thyristor (or silicon-controlled rectifier), invented in about 1950, addressed current-control requirements at higher power ranges, where conventional transistors reach limits related to heat dissipation.

Normal thyristors (silicon-controlled rectifiers) are not fully controllable switches (a "fully controllable switch" can be turned on and off at will).

Silicon-Controlled Rectifier (SCR)

In the electrical schematic to the right, a typical silicon-controlled rectifier (SCR) based light dimmer dims the light through phase angle control.

A static transfer switch uses power semiconductors such as Silicon-controlled rectifiers (SCRs) to transfer a load between two sources.

The TO-220 is a style of electronic component package, commonly used for discrete semiconductors as transistors and silicon-controlled rectifiers, as well as integrated circuits.

Both silicon-controlled rectifiers (SCR) and TRIACs are members of the thyristor family.

Diacs are bi-directional diodes that switch AC voltages and trigger triacs or silicon-controlled rectifiers (SCRs).

Thyratrons have been replaced in most low and medium-power applications by corresponding semiconductor devices known as thyristors (sometimes called silicon-controlled rectifiers, or SCRs) and triacs.

It was the SCR, Silicon-controlled rectifier or thyristor invented in the late 1950s that replaced the troublesome thyratron, and paved the way for a reliable solid-state CD ignition.

Thyratrons containing hydrogen have a very consistent time delay between their turn-on pulse and full conduction; they behave much like modern silicon-controlled rectifiers, also called thyristors due to their functional similarity to thyratrons.

The motors are supplied by traction converters with integrated gate-commutated thyristor (IGCT) rather than silicon-controlled rectifier (SCR) components as in the KTX-I.

Physically, rectifiers take a number of forms, including vacuum tube diodes, mercury-arc valves, copper and selenium oxide rectifiers, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches.

State of the art units now employ SCR (silicon-controlled rectifier), IGBT or MOSFET technologies for generating the 'MF' and 'RF' current.

Since early transistors were not available with sufficient voltage and current ratings for most inverter applications, it was the 1957 introduction of the thyristor or silicon-controlled rectifier (SCR) that initiated the transition to solid state inverter circuits.

She noted that the goods have been referred to as silicon-controlled rectifiers by at least one of the witnesses at the hearing, but there was not enough evidence presented at the hearing to properly determine whether the goods could be classified under tariff item 44544-2.
