The board at a glance
The REF-AIRCON-C302A-IM564 is a part of Infineon’s CIPOS
TM
Mini IPM and iMOTION™ reference design kits. It is
designed to provide ready-to-use, air conditioner solutions based on Infineon’s PFC-integrated CIPOS
TM
Mini
IPM and advanced motion control engine (MCE 2.0) technology.
The REF-AIRCON-C302A-IM564 is an optimized design for 1400 ~ 2500 W power air conditioner applications. It
allows fast prototyping and fast time to market. It is available through regular Infineon distribution partners as
well as on Infineon's website. The main features of this board are described in this document, whereas the
remaining paragraphs provide information to enable the customers to copy and modify the design for
production according to their own specific requirements.
1.1
Delivery content
The board is equipped with all assembly groups for sensorless field-oriented control (FOC), and reserved
interface for BLDC/AC fan control, relays and 4-way valve control and 3-channel temperature sensing circuits,
so that it can be easily used for air conditioners and similar home applications.
It provides a single-phase AC connector, an EMI filter and soft power-up circuit, input rectifier, DC bus
capacitors, on-board PFC inductor emitter shunts for current sensing and overcurrent protection (OCP),
thermistor output and a voltage divider for DC-link voltage measurement.
The REF-AIRCON-C302A-IM564 reference design also contains a CoolSET
TM
based flyback auxiliary power supply
to provide 15 V, 12 V & 5 V.
