Integrated power module

International Rectifier has introduced the IRAMX16UP60A, the latest member of the PlugNDrive family of integrated power modules that simplify variable-speed electronic motor control circuits. The 16 A rated device is designed for 750 W to 1.2 kW variable speed motor drives.

The power modules are part of IR's iMotion family of integrated design platforms, incorporating a three-phase inverter power stage with gate drivers and auxiliary circuitry in a compact, high performance, isolated package.

The device combines IR's low loss, non-punch-through short circuit-rated IGBT with a three-phase, high-voltage, high-speed driver IC and over 20 individual parts into a single unit.

The module, plus a few external components and one microcontroller, enables a complete variable speed motor drive. EMI emissions are minimised due to shorter connection routing, optimised component layout and internal shielding.

An open emitter configuration facilitates the implementation of several motor algorithms. Using the IRAMX16UP60A PlugNDrive module enables multi-shunt current feedback for a sophisticated vector control loop, in V/Hz control loop, with no circuit layout limitation.
