PFC and inverter stage are integrated into the IRAM630-1562F intelligent power module (IPM) from International Rectifier. The IRAM630-1562F module shrinks and simplifies design of energy-efficient appliance and light industrial motordrive applications including air conditioners and washing machines, says the company.

It combines 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, under-voltage lockout function and temperature monitor protect for fail-safe operation. Other integrated features are bootstrap diodes for the high-side drive function and single polarity power supply to simplify the system design. The open emitter configuration enables multi-shunt current feedback for a vector control loop in V/Hz control loop. Over-temperature is detected internally and triggers a fault condition.
