Three-Phase Inverter Integrated PFC

Three-Phase Inverter Integrated PFC

The IRAM630-1562F Intelligent Power Module (IPM) from International Rectifier features Power Factor Correction (PFC) and an inverter stage. The new IPM shrinks and simplifies design 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 minimized due to shorter connection routing, optimized component layout and internal shielding.

The new IPM is an addition to IR's iMOTION™ design platform which integrates digital, analog 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.

Pricing for the IRAM630-1562F2 begins at US $12.75 each in 10,000 unit quantities. Production quantities are available immediately.
