What is Power Electronics

Power electronics is the application of solid state electronics to the Control and convention of electric power.

It is also refers to a subject of research in electronics and electrical engineering, which deal with the design and Control, Computation and integration of non-leaner, time varying, energy Processing electronic system with fast dynemes.

The Power Convention system can be classified according to the types of input and output.

What is Rectifier

A Rectifier is an electronic device that convert Alternative Current to direct current, Physically rectifiers take a number of forms including semi conductors, diode rectifiers, silicon control rectifiers and Silicon hose Semi Conductor Switch.

Users of rectifiers often Bounds Serving as Components of DC Power Supply and high voltage DC power transmission system.

Applications of rectifiers

Power Supply of rainfall, Television, Computer Equipment In those cases output of the rectifier is Smooth by electronic filter usually known as capacitor.

What is a Half-Wave Rectifier?

A half-wave rectifier converts an AC signal to DC by passing either the negative or positive half-cycle of the waveform and blocking the other. Half-wave rectifiers can be easily constructed using only one diode, but are less efficient than full-wave rectifiers.

Since diodes only carry current in one direction, they can serve as a simple half-wave rectifier. Only passing half of an AC current causes irregularities, so a capacitor is usually used to smooth out the rectified signal before it can be usable.

Full Wave Rectifier

What is a Full-Wave Rectifier?

Diode Bridge Rectifier
Center Tapped Rectifier

Power Diodes can be connected together to form a full wave rectifier that convert AC voltage into pulsating DC voltage for use in power supplies

The full wave rectifier converts both halves of each waveform cycle into pulsating DC signal using four rectification diodes. In the previous power diodes tutorial we discussed ways of reducing the ripple or voltage variations on a direct DC voltage by connecting smoothing capacitors across the load resistance.
