Spread Time (ts)
During spread time anode voltage falls from 10% Ia to the on state voltage drop and anode current rises from 90% Ia to final value of anode current i ,e Ia in this period whole charges injected from gate spreads over the entire section of cathode and anode current reaches at steady state condition.
There the total turn on time ( ton ) can be written as
Ton = td + Ir + ts
In these intervals td tr and ts the rise time is high a s compared to other. If rise time it is reduced beyond a limit thyrisotr may get destroyed because rate of rise of anode current may be large as compared to the spread velocity of charges and this may forms a local hot spot on the cathode surface of SCR. Turn on time depends on gate current. It can be reduced by using higher value of gate currents.
how over compensation by capacitive var rises voltage in a circuit?
To demonstrate a practical method of testing semiconductor diodes.
An induction motor takes 350 kW at 0.8 power factor lagging while driving a load. When an overexcited synchronous motor taking 150 kW is connected in parallel with the induction mo
