thyristor
A well-known method of handling this problem is to use gates, attached directly to the bases of a thyristor.
      
A binary weighted compensation current is short circuited to ground by the thyristor or this current goes to the compensation node in the off-mode.
      
A three-phase six-pulse thyristor rectifier with an inductive dc load was used as a harmonic-producing load.
      
All communication between the control equipment at earth potential and each thyristor at high potential is done with fibre optics.
      
All switching is done with precision ensuring there is no stress to either the capacitors or to the thyristor switching devices.
      
As for electric cars, the 726kW 600V Thyristor rectifier was made for Series 711 suburban AC trains in 1967.
      
At that point, the anode-to-cathode thyristor voltage vAK begins to be positive.
      
As already implied in the Introduction, the ideal semiconductor switch should be a thyristor in the conducting state only.
      
At the positive voltage on the anode and negative or zero at the gate, MOS thyristor blocks the current from cathode to anode.
      
As is well known, TCRs require a high-rated thyristor system, and this is the main cause of their unreliability.
      
At a voltage of approximately 6V, the zener diode D15 breaks down and turns on transistor Q10, which then turns off transistor Q6 and the thyristor.
      
By sensing the floating n voltage, the protection circuit alters the operation mode of the thyristor from regenerative to nonregenerative.
      
Basically, a thyristor element is employed to control the timing to apply trigger voltage.
      
Based on the evaluation of both technologies, the thyristor based battery charger performs better.
      
Control of the dynamometer is fully regenerative by a four-quadrant thyristor drive.
      
Components of the thyristor modules which make up a valve or quadrivalve.
      
Conventional HVDC transmission using line-commutated thyristor valves is characterized by very high transmission voltage and power.
      
Chapter 3 discusses the development, simulation, operation and experimental results of a thyristor based battery charger.
      
Due to its slow switching a normal thyristor is only suitable up to a few kHz.
