थायरिस्टर इसके अंग्रेजी अर्थ का उदाहरण

It works by modulating a thyristor, SCR, triac, thyratron, or other such gated diode-like devices into and out of conduction at a predetermined phase of the applied waveform.

Most phase-fired controllers use thyristors or other solid state switching devices as their control elements.

Thyristor-based controllers may utilise gate turn-off (GTO) thyristors, allowing the controller to not only decide when to switch the output on but when to turn it off, rather than having to wait for the waveform to return to zero.

It became widespread with the invention of solid-state thyristors at the end of the 1950s.

This is then converted to direct current before being converted to three-phase electricity through one of three gate turn-off thyristors.

The solution seemed to be thyristor locomotive that had successfully been tested by ASEA and Canadian Pacific Railway with possibilities to pull 50% heavier trains than equivalent diesel electric locomotives were capable of.

The six traction motors are supplied with three-phase electrical power by gate turn-off thyristor controlled inverters using pulse-width modulation controlled by a Siemens' Sibas-32 traction control electronics.

The 69-set was also given new thyristor motors with 1,200"nbsp;kW, a lot more than the old units.

The first to be introduced were the AC Class 317, built in two batches from 1981–82 and 1985–87 with thyristor control systems.

Class 319 was built in two batches in 1987–88 and 1990 with gate turn-off thyristor control systems.

In preparation for the changeover, a new series of cars called EW58 had been developed, incorporating technical innovations such as thyristor controls, anti-wheel-slip devices and so forth, which were expected to provide major improvements.

It is likely that a thyristor (SCR) power controller using the variable phase angle method will generate harmonics of the mains supply, while the spark at a contact will be a very wide band source whose frequency is not related to the power supply frequency.

In Thyristor control systems the potential for EMI problems can be minimised by using zero crossing switching where the thyristor is switched on at the moment of time when the AC voltage changes from one direction to the other.
