A thyristor (/ θaɪˈrɪstər /) is a solid-state semiconductor device which can be thought of as being a highly robust and switchable diode, allowing the passage of current in one direction but not the other, often under control of a gate electrode, that is used in high power applications like inverters and radar generators.
One six-pulse bridge consists of the even-numbered thyristors, the other is the odd-numbered set. Although better than single-phase rectifiers or three-phase half-wave rectifiers, six-pulse rectifier circuits still produce considerable harmonic distortion on both the AC and DC connections.
A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current -controlling device. The name "silicon controlled rectifier" is General Electric 's trade name for a type of thyristor. The principle of four-layer p–n–p–n switching was developed by Moll, Tanenbaum, Goldey, and Holonyak of Bell ...
IXYS Introduces the ComPack Thyristor Module Platform - a New Design That Reduces Parts and Material Costs with Higher Power Density BIEL, Switzerland--(BUSINESS WIRE)-- IXYS Corporation (NAS ...
A thyristor-switched capacitor (TSC) is a type of equipment used for compensating reactive power in electrical power systems. It consists of a power capacitor connected in series with a bidirectional thyristor valve and, usually, a current limiting reactor (inductor). The thyristor switched capacitor is an important component of a Static VAR ...
The difference between "Plummer’s device" and "Becke’s device" is that "Plummer’s device" has the mode of thyristor action in its operation range, but "Becke’s device" never has the mode of thyristor action in its entire operation range. This is a critical point, because the thyristor action is the same as so-called "latch-up".
A bidirectional transient-voltage-suppression diode can be represented by two mutually opposing avalanche diodes in series with one another and connected in parallel with the circuit to be protected. While this representation is schematically accurate, physically the devices are now manufactured as a single component.
A Voltage controller thyristor based dimmer rack An electrical schematic for a typical SCR-based light dimmer. A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, triodes for alternating current, silicon-controlled rectifiers or insulated-gate bipolar transistors, which converts a fixed voltage, fixed frequency ...
