IR Introduces Proprietary Plastic Packaged Motor Inverter Modules that Deliver High Reliability in Airborne Motor Control Systems
International Rectifier has introduced two new near-hermetic, high-reliability (HiRel™) motor control inverter modules that combine IR’s latest IGBT and soft recovery rectifier technology with IR’s proprietary plastic package sealing method to protect components from environmental conditions.
The new devices are designed to enhance three phase motor control circuits in electro-hydrostatic applications (EHA) such as critical flight controls for aircraft. Other applications include aircraft braking and refueling systems, electric vehicle motor control, and ground vehicle power generation systems. “IR developed the proprietary sealing process to address the need for high reliability critical flight controls” said Rick Furtney, International Rectifier Vice President, HiRel Sector Business Unit.
The IGBT modules come in the new HiRel™ INT-A-Pak 2 package, which uses an encapsulation process that protects circuitry from the harmful effects of moisture, and are screened to the stringent environmental test conditions of MIL-PRF-38534, Class H. Components screened in accordance with these specifications meet the high reliability requirements demanded by the defense contractors supplying to commercial OEMs in vital safety applications and the US Military.
