Thus, the main metric of power electronics becomes the efficiency. The first very high power electronic devices were mercury arc valves. In modern systems the conversion is performed with semiconductor switching devices such as diodes,thyristors and transistors. Power Electronics defined as the application of solid-state (devices) electronics for the control and conversion of electric power. Power Electronics Application Power electronics have already found an important place in modern technology and are now used in a great variety of high-power product, including heat controls, light controls, electric. • A third classification is based on the degree of controllability: uncontrollable switches (diodes), semi-controllable switches (thyristors), and fully-controllable switches (BJT, MOSFET, JFET, IGBT, GTO, MCT) Brief History. • Power semiconductor devices first . Power electronics is an interdisciplinary subject within electrical engineering. A power electronic system consists of power electronic switching devices, linear circuit elements, digital circuits, microprocessors, electromagnetic devices, DSPs, filters, controllers, sensors, etc. Fast recovery diodes: Fast recovery diffused diodes and fast recovery epitaxial diodes, FRED's, have significantly lower Qrr and trr (~ ˜sec). They areavailable at high powers and are mainly used in association with fast controlled-devices as free-wheeling or DC-DC choppers and rectifier applications. Power semiconductors are the heart of power electronics equipment. Snubbers are circuits which are placed across semiconductor devices for protection and to improve performance. Power electronic switching device is a combination of active switchable power semiconductor drivers which are integrated into one. Major distinctiveness of the switch will be determined by the inner association of functions and interactions of its integrated system. Below figure displays how a power electronic switch system will work. Power electronics based on the switching of power semiconductor devices. With the development of power semiconductor technology, the power handling capabilities and switching speed of power devices have been improved tremendously.
