Switching characteristics during turn on
A positive gate pulse between gate and cathodeis sufficient to turn on a thyrisotr. In this period thyristor changes its state from forward off blocking state to on state and starts conduction. Time is turn on time of a thyristor which can be divided into three intervals.
a.Delay time (td)
b.Rise time (tr) and
c.Spread time ( ts)
Write a short note on RS-232-C. The RS-232 standard is a collection of connection standards among different pieces of equipment. The EIA RS-232 serial communication standard is
Q. JFET Common Drain Amplifier? The common drain FET amplifier is similar to the common collector configuration of the bipolar transistor. A general common drain JFET amplifier
Q. Explain Fourier Series? The phasor method of circuit analysis can be extended (by using the principle of superposition) to find the response in linear systems due to nonsinu
A Zener diode has the specifications VZ=6.8V and PDmax.=500mW. Assume RZ=0. (a) Find the maximum allowable current iZ when the Zener diode is acting as a regulator. (b) If a sing
Define Johnson Counters to Produce a Time Delay? The "serial in-serial out" shift register can be used as a time delay device. The amount of delay able to be controlled by:
Assume a ray of light is incident on a smooth reflecting surface at an angle of incidence of 15 degrees to the normal. What is the angle between the incident ray and the reflected
Scatter Diagrams - Quality Tools for Improvement Scatter diagrams are graphical tools which attempt to depict the influence in which one variable has on another. A general dia
Q. Explain the basic principle of linear sweep voltage generator A linear time base generator or sweep generator is one that provides an output waveform, a portion of which exh
Q. A sectional view of a cylindrical iron-clad plunger magnet is shown in figure. The small air gap between the sides of the plunger and the iron shell is uniform and 0.25 mm long.
Bias circuit requirements: Signal requirements for Class A amplifiers The Q-point is placed thus the transistor stays in active mode (does not shift to operation in the s
