Powerex was established in 1986 as the combination of the power semiconductor businesses of GE and Westinghouse Electric and currently employees 190 people in the US. Mitsubishi took over the Westinghouse shares in 1994.
The companies supplies discrete devices, modules and integrated high power semiconductors, including IGBTs (Insulated Gate Bipolar Transistors), HVIGBTs, IPMs (Intelligent Power Modules), rectifiers, thyristors, custom power modules and assemblies, making rectifier and thyristor products at its Youngwood, PA factory. It also provides sales, marketing, strategy and logistics support for Mitsubishi Power Semiconductor devices in the Americas.
Powerex supports many markets, from AC, DC and Servo Drives, Alternative Energy (Wind, Photovoltaic) and Distributed Power (Flywheel, Fuel Cell, Microturbine), Induction Heating, medical power supplies and power generation to pulsed power and UPS systems.
The Mitsubishi deal sees Powerex becoming part of Mitsubishi Electric US as the Americas are a key region due to the projected growth of the region's automotive market. The deal will provide stronger customer support for global manufacturing networks based in the Americas as well as stronger collaboration and technical support for the automotive market and car makers, says Mitsubishi. It will also allow for more sharing of resources among existing business units within Mitsubishi Electric US.
Following the acquisition in January 2018 Mitsubishi Electric will continue to support Powerex's business development.
