An intelligent power module has been developed by International Rectifier featuring Power Factor Correction and inverter stage that helps shrink and simplify design
of energy-efficient appliances and light industrial motordrive applications.
The IRAM630-1562F combines the company’s low loss, Trench IGBTs with a three-phase, high-voltage gate drive IC and PFC input stage, which is an integration of more than 30 components in this single compact isolated package. Built-in over-temperature/over-current protection, along with an integrated under-voltage lockout function, and built-in temperature monitor ensure a high level of protection and contribute towards a 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.
Replacing more than 30 discrete parts, IR’s compact IRAM630-1562F delivers a complete, reliable power stage solution for today’s energy-efficient motor drives featuring both PFC and inverter stages. By using this device with just a few external components and one microcontroller, design cycles and overall system costs for appliance variable speed motor projects are significantly reduced compared to discrete solutions,” said Alberto Guerra, Vice President, Strategic Market Development, IR’s Energy Saving Products Business Unit.
The device features an open emitter configuration that 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 company advises its new IPM is in addition to its iMOTION design platform which integrates digital, analogue and power technologies.
