Power electronics is the application of solid-state electronics to the control and conversion of electric power. In modern systems, the conversion is performed with semiconductor switching devices such as diodes, thyristors, and power transistors such as the power MOSFET and IGBT.Power Electronics is the technology associated with efficient conversion, control and conditioning of electric power from its available input into the desired electrical output form.Power electronics has found an important place in modern technology being a core of power and energy control. Almost all the new electrical and electromechanical equipment contain power circuits. The power levels encountered in this field range from less than one watt in supplies for the battery-operated portable equipment to tens, hundreds, or thousands of watts in power units of office equipment, kilowatts to megawatts in variable-speed motor drives, approaching megawatts in the rectifiers and inverters that interface the local transmission lines with the high power systems.
