Welcome to your Power Electronics
The SCR is turned-off when the anode current falls below
holding current
forward current rating
latching current
breakover voltage
In a SCR circuit, the angle of conduction can be changed by changing
forward current rating
anode current
gate current
anode voltage
For thyristors, pulse triggering is preferred to triggering because
gate dissipation is low
Triggering system is required for a very short duration
pulse system is simplier
all of the options
The normal way to close a SCR is by
gate current
anode current
cathode current
forward current
Which of the following conditions is necessary for triggering system for thyristors?
It must use separate supply
It should be syncronized with the main supply
It should provide a train of pulses
Current must be zerro
