Powerelectronics may be defined as the applications of solid-state electronics for control and conversion of electrical power.Powerelectronics are based primarily on the switching of the power semiconductor devices. Power electronics combine power, electronics and control. Powerelectronics have already found an important place in modern technology and are now used in a great variety of high-power products, including heat controls,light controls, motor controls, power supplies, and high voltage direct current systems.

AC-AC Converter:
An AC/AC converter converts an AC waveform such as the mains supply, to another AC waveform, where the output voltage and frequency can be set arbitrarily.
DC-AC Inverter:
An inverter is an electrical device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.
AC-DC Rectifier:
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which is in only one direction, a process known as rectification. Rectifiers have many uses including as components of power supplies and as detectors of radio signals. Rectifiers may be made of solid state diodes, silicon-controlled rectifiers, vacuum tube diodes, mercury arc valves, and other components.
DC-DC Converter:
A DC-to-DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. It is a class of power converter.
