When the load current exceeds the rating of a single SCR, SCR’s are connected in parallel to increase their common current capability.
Rectification is the process of converting alternating current or voltage into direct current or voltage.
Full-wave rectifier are more commonly used than half-wave rectifier, due to their higher average voltages and currents, higher efficiency, and reduced ripple factor.
This is the circuit diagram of a simple UPS that can deliver 12V unregulated and 5V regulated DC. The transformer T1 steps down the mains voltage to 12V AC and then the bridge B1 rectifies it.
Some time disturbance of power supply creates a number of problems. Especially in sensitive departments such as Radar System
An Inverter is a device that converts 12 volts dc to 120 volts ac, which is what we use in our homes.
The multi-voltage supply circuit shown relies on a multi-winding transformer to generate several AC voltages from a single AC input.
The transistor is used to amplify the weak signal a CE amplifier connection is shown in below figure.
Zener diodes are used to maintain a fixed voltage. They are designed to 'breakdown' in a reliable and non-destructive way so that they
In voltage multiplier circuit two or more peak rectifiers are cascaded to produce a d.c voltage equal to multiplier of the peak input voltages
Triode is a vacuum tube with three electrodes which are cathode, Anode and a control grid. The function of additional third electrode
A Vacuum tube diode is a two electrode vacuum tube as its name shows DI for two ODE for electrodes. The two electrodes are cathode and anode (plate).
This diode was first introduced by Dr. Leo Esaki in 1958. It is called a tunnel diode because due to its extremely thin depletion layer,
