EL SEGUNDO, Calif. February 2004 - International Rectifier, IR® (NYSE: IRF), the world leader in power management technology, today introduced three new advanced integrated power modules (IPMs), expanding the iMOTION™ family of integrated power modules. The new IPMs simplify variable-speed electronic motor control circuits commonly found in today's energy-efficient appliances and feature a three-phase inverter power stage with gate drivers and auxiliary circuitry in a compact, high-performance, isolated package.

All three new devices combine IR's low loss, non-punch-through (NPT) short circuit-rated IGBT with a three-phase, high-voltage, high-speed driver IC and over 20 individual parts into a single unit. The new modules, plus a few external components and one microcontroller, enable a complete variable-speed motor drive. EMI emissions are minimized due to shorter connection routing, optimized component layout and internal shielding.

The 6A-rated IRAMS06UP60A and IRAMS06UP60B are designed for motor drive applications in appliances and light industrial products such as compressors in refrigerators or fan controllers in heating and ventilation systems up to 400W. The IRAM06UP60A has open emitter configuration and therefore enables multi-shunt current feedback for sophisticated vector control loops.

The IRAMS10UP60B includes a current feedback shunt, and is designed for appliances such as air conditioners and energy-efficient washers up to 750W. The IRAMS06UP60B is the best choice for simplified V/Hz control type motor drivers, with no circuit layout limitations.

Alberto Guerra, Director, Consumer & Industrial Business Unit at International Rectifier said, "The iMOTION integrated power modules save design time, decrease system cost and are ideal solutions for variable-speed appliance motors. Variable-speed motors can reduce energy use by up to 30%. They are the right answer for manufacturers of advanced appliance products, such as energy-saving washing machines and refrigerators."

The new IRAMS06UP60A is pin-to-pin compatible with the existing IRAMS10UP60A and IRAMX16UP60A, giving the Motor Control designer a simple path to upgrade or expand power level offerings in existing designs.

Built-in over-temperature and over-current protection and integrated under-voltage lockout functions deliver fail-safe operation. Bootstrap diodes in the high-side driver section combine with the required single-polarity power supply to simplify circuits. In addition, all new IPMs include a temperature monitor read-back signal and synchronized shut down function.
