Power Modules

International Rectifier (IR) recently 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 3-phase inverter power stage with gate drivers and auxiliary circuitry in a compact, high-performance, isolated package.

All three devices combine IR’s low loss, non-punch-through (NPT) short-circuit rated IGBT with a 3-phase, high-voltage, high-speed driver IC and more than 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 6-A 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 400 W. The IRAM06UP60A has an open emitter configuration and therefore enables multi-shunt current feedback for sophisticated vector control loops.

The IRAMS06UP60B includes a current feedback shunt, and is designed for appliances such as air conditioners and energy-efficient washers up to 750 W.
