Infineon – REF-AIRCON-C302-IM564

REF-AIRCON-C302-IM564The reference design for motor control in residential aircon applications, REF-AIRCON-C302-IM564 is a 3-phase turnkey motor drive for air conditioner outdoor units (ODU) with anIMC302iMOTION™ controller, a CIPOS™ Mini IPMIM564-X6Dinverter with integrated PFC stage, a1ED44175gate driver for the PFC stage and a CoolSET™ICE5AR4770BZSfor the auxiliary supply.

Features
– Typical 1400 W motor power with heatsink cooling
– Maximum 2500 W motor power with forced convection
– Input voltage rage of 85…265 VAC incl. on-board auxiliary voltage supply
– On-board inductor for 40~60 kHz PFC operation
– Control interfaces to external BLDC or AC fan, 4-way valve and temperature sensor
– Communication interface to indoor unit (IDU)
– Overcurrent and over temperature protection and a fault diagnostic LED output
– Small 2-layer PCB with 250 mm × 157 mm
– Easy-to-use iMOTION™ control firmware

Benefits
– Excellent PFC performance (power factor=0.999 and THD=3.4% measured for typical use case of 1400 W)
– Up to 15% PCB space savings compared to discrete implementa-tion
– All interfaces for a complete system solution are on-board and can be controlled by Software
– Ready-to-use motor control algorithms (incl. PFC) for high-efficiency permanent magnet synchronous motors (PMSM)

Competitive advantage
– A reference designs, which helps to design outdoor units (ODU) more efficient, denser and faster :
– Efficiency -Excellent PFC performance with a power factor (PF) of 0.999 and a total harmonic distortion (THD) of 3.4% at 1.4 kW
– Size -Up to 15% smaller design compared to discrete im-plementation
– Speed -Reduced time to market by concentrating on appli-cation development rather than on motor control

Target applications
– Residential aircon -motor-, system control and monitoring
