Reference boards enable efficient control of rotary fridge compressor drives

Infineon Technologies has introduced two new reference boards that have neem designed for rotary refrigerator compressors.

Both are turnkey solutions for low power compressors that can be copied by customers to build final mass-production application boards. Since the design of the reference boards is system tested developers will be able to drastically reduce their own system development time.

The REF_Fridge_D11T_MOS is a ready-to-use three-phase inverter including the iMOTION Smart Driver IMD111T-6F040 and the 600 V CoolMOS PFD7 superjunction MOSFET IPN60R1K0PFD7S.

The board provides an easy-to-use power stage based on the iMOTION smart driver that combines ready-to-use FOC motor control algorithms with 600 V phase gate driver in LQFP-40 package. It also includes the discrete CoolMOS superjunction MOSFET with lowest Q rr, ESD protection and a compact SOT-223 surface mounted device (SMD) package. The board can be interfaced through iMOTION Link and enables best light-load efficiency as well as providing a compact design.

The reference design REF_Fridge_C101T_IM231 is intended for customers aiming for a higher level of integration and a reduced footprint. The board combines a digital motor control IC (iMOTION) IMC101T-T038 with a three-phase CIPOS Micro intelligent power module based on an 6 A, 600 V IGBT. This combination provides a fully-featured compact inverter solution for low power motor drive applications.

Furthermore, it enables BOM count and PCB size reduction and improves reliability.
