Bistable Multivibrator - Working and Types: A bistable multivibrator, as its name implies, has two stable states. It can stay in either of the two states indefinitely (as long as…
Monostable Multivibrator - Operation, Types and Application: Monostable multivibrator is a two-stage amplifier with two states—one stable state and another quasi-stable state. The circuit has two transistors Q1 and Q2,…
Astable Multivibrator Definition and its Working: The multivibrator circuit which has no stable state is called the astable multivibrator. The two states of operation of astable multivibrators are quasi-stable (temporary)…
Multivibrator definition and Types (Astable, Monostable and Bistable): A multivibrator is basically a two stage R-C coupled amplifier with positive feedback from the output of one amplifier to the input…
Switching Characteristics of Power MOSFET: Power MOSFET is an enhancement mode device modified to handle much large currents and voltages than a conventional MOSFET. Prior to the invention of the…
What is Switching Circuit? In practice, we often need making (switching on) and breaking (switching off) of an electrical circuit. It is also desirable and sometimes essential that the switching…
Step Down Chopper with RLE Load Working Principle: The choppers are widely employed for speed control of dc motors in industrial and traction drives. Figure 27.30 (a) shows the basic…
What is a Power Converter? Solid-state power converter are employed for obtaining the approÂpriate form of electrical energy such as direct current or adjustable-frequency alternating current (required to operate most…
