Fast Thyristors.
Fast Thyristors.
Fast thyristors are used in static power converters, and in various DC and AC power units with a frequency of up to 5,000 Hz, where short on/off switching intervals are required; in various types of electric welding equipment, in frequency converters for electrothermics, in traction systems of electric locomotives and electrified urban transport vehicles, in air ozonizers, in generators, and in modulators.

Avalanche thyristors are used in static power converters and in other DC and AC circuits with a frequency of up to 1,000 Hz. Under certain conditions of reverse voltages, they can be used without any additional protection measures.

Voltage suppressors are rectifier avalanche diodes that dissipate power pulse in the breakdown region of the reverse volt-ampere curve within a limited period of time. They are used for protection of semiconductor power devices and capacitors from switching surges, as well as to limit voltage in electrical equipment at frequencies up to 500 Hz.
