International Rectifier (IR) has announced the IRAM630-1562F intelligent power module (IPM) featuring power factor correction (PFC) and inverter stage. According to the firm, the IPM shrinks and simplifies designs of energy-efficient appliance and light industrial motor drive applications including air conditioners and washing machines.

The IRAM630-1562F combines IR's low loss, trench IGBTs with a three-phase, high-voltage gate drive IC and PFC input stage, integrating more than 30 components into a single compact isolated package. Built-in over-temperature/over-current protection, along with an integrated under-voltage lockout function and built-in temperature monitor provide for a high level of protection and fail-safe operation. Other integrated features such as bootstrap diodes for the high-side drive function and single polarity power supply simplify the system design while reducing overall cost.

The IRAM630-1562F's open emitter configuration enables multi-shunt current feedback for a sophisticated vector control loop, in V/Hz control loop, with no circuit layout limitation. Over-temperature is detected internally and triggers a fault condition. EMI emissions are minimised due to shorter connection routing, optimised component layout and internal shielding.

The IPM is an addition to IR's iMOTION design platform that integrates digital, analogue and power technologies together in a flexible, mixed signal chipset to simplify motor control designs and bring energy-efficient, cost-effective solutions to market faster.

The 15A IRAM630-1562F has a 2kW maximum motor power, 30A peak PFC current and is available in SIP2 package.
