Range Hoods
Leveraging the full-chain synergy of its IDM model, crmicro provides customers with complete solutions for high-reliability chargers, battery management, brushless motor control, and main controllers, as well as semiconductor devices，which helps end products (daily small appliances) achieve high efficiency, reliability, safety, intelligence, long runtime, and user-friendly operation.
Solution Overview
Targeting the electronic control system of household range hoods, the solution covers the full chain: main power supply, variable-frequency fan drive, lighting control and signal sampling. Using power devices (IPM/IGBT/SiC MOSFET/SiC diode), multiple PMICs, general-purpose and motor-specific MCUs, and optocouplers, it enables efficient variable-frequency speed regulation of the fan and stable system power supply, improving overall operating energy efficiency and long-term reliability.
Solution Advantages
-
Energy saving & high efficiency
-
Variable-frequency control extends motor life
-
Not sensitive to motor parameter variations, adapting to complex operating conditions
-
Low noise during operation
