By controlling the trigger pulse, TCSC can transform the trigger angle of thyristor.
Further, the company sqaid it will not transfer any manufacturing assets related to the divestiture of the Ignition IGBT business or the sale of the TVS and thyristor businesses and both asset sales are expected to close on 29 August 2016.
The report covers the present scenario and the growth prospects of the global thyristor market for 2016-2020.
2) [7] realized, which includes the following structural elements: electricity network (Three-Phase Source) with equivalent inductive and active resistance; "non-linear load" connected to the mains through the reactor (Reactor 2) which is represented by thyristor converter (Thyristor Converter) with active-inductive load (RL-load); three-phase transistor converter (Transistor converter); Current generation block and Pulse shaping block.
It is difficult to check the fact of thyristor locking, so the algorithm of windings contrrol should assume quite a long pause (a few tens of milliseconds) between operations, else a command injection to unlock the transistor VT and thyristor VSO at open thyristor VSI will not lead to the disconnection of the switching device and can cause a serious accident if it is necessary to disconnect the device immediately after switching it to a short circuit.
This is achieved using the newly developed Dynamic Thyristor Diagnostic (DTD) programme, which monitors the unit and the load on it, in real-time.
Common cathode thyristor converter is constructed from 2-thyristor and 2-diode whereas single thyristor diode bridge converter is developed from single thyristor and 4- diode.
Capable of performing at temperatures up to 300 C and current at 80 A, the SiC Thyristor offers up to 10 times higher voltage, four times higher blocking voltages, and 100 times faster switching frequency than silicon-based thyristors.
By utilizing thyristor switched capacitors (TSC), the SVC provides stepped control with low losses and no harmonics.
The maximum forward switching voltage is the value of applied voltage when thyristor switches from the off to the on state and the voltage is not applied to the control terminal.
