The Power electronics circuits convert electric power from one form to another using electronic devices. The Power electronics circuits works by using semi-conductor devices as switches, thereby controlling or modifying a current or voltage. There are various applications of power electronics ranging from high-power conversion equipment includes dc power transmission to everyday appliances, including following
Applications Power electronics includes those applications in which circuits process milli-watts or mega-watts. Very Typical applications of power electronics includes the following
- conversion of ac to dc,
- conversion of dc to ac,
- conversion of an unregulated dc voltage to a regulated dc voltage, and
- conversion of an ac power source from one amplitude and frequency to another amplitude and frequency.
The design of power conversion equipment calls for many disciplines from electrical engineering. The other Power electronics applications includes the following
- circuit theory,
- control theory,
- electronics,
- electro-magnetics,
- microprocessors (for control), and
- heat transfer.
Improvements and developments in semiconductor switching capability combined with the willingness to improve the efficiency and performance of electrical devices have led field power electronics an important and ever-growing area in electrical engineering.
