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.
Buck Boost Converter The output of buck boost regulator may be less than or greater than the input voltage. Since the polarity of output voltage is opposite to that
What is a control word? It is a word kept in a register (control register) used to control the operation of a program digital device.
What are advantages of segmentation ? However because the segment register is 16 bit broad and the memory requires 20 bits for an address the 8086 appends 4 bits segment reg
Which clipper would you prefer between the series and the shunt clipper? Why?
Q. At the two terminals (A, B) of a one-port network, the voltage and the current are given to be v(t) =200 √2 cos (377t + 60°) V and i(t) = 10√2 cos(377t + 30°) A. (a) Determin
4GLs (Fourth Generations Languages) These are called non procedural languages May be considered as advanced HLL. Objects oriented programming languages and language with
Q. Explain the working of depletion MOSFET ? The gate voltage can control the resistance of the n-channel but as the gate is insulated from the channel, we can apply either a p
Using a levitation coil, you levitate a conductive object in the magnetic field and heat within that field. I have 2 sample report and I would like you to write some thing similar
A 500KVA, 6 pole, 500v, 3 phase, wye-connected synchronous generator has a synchronous impedance of 0.1 + j1.5 ohms per phase. If the generator is driven at 1000 r.p.m., what is th
Q. Explain common base configuration? Common-base transistor amplifiers are so-called because the input and output voltage points share the base lead of the transistor in commo
