Leveraging the full-chain synergy of its IDM model, crmicro provides customers with complete solutions for high-reliability brushless motor control, compressors, PFC and main controllers, as well as semiconductor devices，which helps customers achieve efficient, energy-saving, stable and reliable home appliances.
Solution Overview
Targeting household refrigeration systems, the solution covers the full hardware chain: low-temperature auxiliary power, variable-frequency compressor drive, main control sampling, and user display. Relying on power devices (IGBT/SiC MOSFET/SiC diode/IPM), power management ICs, main/motor-control MCUs, and op-amps, it optimizes low-temperature standby power consumption, ensures stable compressor operation across wide temperature ranges, and helps miniaturize the overall system while improving reliability.
Solution Advantages
-
Energy saving & high efficiency lead to low operating cost
-
Variable-frequency control extends motor life
-
Not sensitive to motor parameter variations, adapting to complex operating conditions
-
Low noise during operation
