Power Electronics Devices

Power electronics devices are solid-state devices or transistors capable of modulating or converting electrical power. A power electronic device enables the production of power management modules that can handle all of the electric power control and conversion functions required to move power from the generating and storage sources to the ultimate loads. Electric energy will play an increasingly important role in future energy system because of its controllability, safety, and high efficiency. Power electronics devices will be used at every point at which electric energy is converted to or from another type of energy.

Power electronics devices function in a variety of ways. Power semiconductor devices are used as switches or rectifiers in high-power electronic circuits. Power semiconductor devices are also power electronics devices or when used in integrated circuits, they are called power ICs. A high voltage insulator is used in the transmission or distribution of electrical energy or for use as a part of a large electrical machine or piece of equipment. A high voltage insulator has a high resistance to puncture through the material of the insulator to the pin or supporting medium. An electronic voltage regulator is almost exclusively used in industrial settings. An electronic voltage regulator can also deliver 1000% fault clearing current to downstream breakers. The output voltage can be raised or lowered by ± 10% by adjusting a control potentiometer. A high voltage regulator is best used with motor loads and other high inrush devices. A DC to DC regulator features synchronous, integrated power FET transistors and is used in applications with a 5-V input generating an output of 3.3 V. A DC voltage regulator can deliver a continuous load current. An insulated gate bipolar transistor (IGBT) enables switching at relatively high levels of voltage and/or currents, (6.5 kV, 1000 A), and at frequencies of up to 20 kHz using different gate power transmission topologies.

Power electronics devices are utilized in a variety of distributed power applications including telecommunications, data communications, networking, modems, and graphics accelerators. Power electronics devices are also used to assemble functioning power conversion units for Navy power electronics. Power electronics devices are not only applicable to power networks, but also to energy management systems in buildings or automobiles. There are three main types of compliance test for power electronics devices: emissions tests, immunity tests, and safety tests.
