In the heat dissipation and ventilation scenarios of industrial equipment and home appliances, the stability and energy efficiency of onboard DC fans directly affect the overall performance of the machine. ABL Semi (ablsemi.com) has launched an integrated MCU+IPM onboard DC fan drive solution, which provides highly competitive technical support for various fan applications and adapts to the personalized needs of multiple scenarios with its flexible sampling method, reliable startup algorithm and multiple control modes.
Core architecture of the solution: MCU + IPM collaborative optimization of fan control
This solution uses an “MCU main controller + IPM intelligent power module” as its core architecture to build a highly efficient and collaborative control system.
- The sampling method is compatible with both three-resistor and single-resistor modes, allowing customers to flexibly choose according to their cost and accuracy requirements, thus simplifying hardware design complexity.
- The MCU integrates rich peripherals and signal processing functions, and with the highly integrated drive characteristics of the IPM, it reduces the redundancy of peripheral devices and improves the stability and space utilization of the solution.
Key features and highlights: Adaptable to diverse application scenarios
ABL Semi’s onboard DC fan solution achieves multiple breakthroughs in performance and compatibility:
- An improved sensorless algorithm supports direct closed-loop rapid start-up, ensuring stable startup even under complex conditions such as tailwinds and headwinds, avoiding startup failure issues;
- It offers multiple control modes, covering open-loop control, constant speed control, constant power control, and constant airflow control, and supports seamless switching between modes to adapt to different usage scenarios;
- It features offline parameter recognition, making it compatible with various fan motors with different parameters, eliminating the need for additional custom development and reducing customer adaptation costs.
Suitable Scenarios: Covering Multiple Fan Applications
This solution can be widely used in various devices requiring onboard DC fans:
- Home Appliances: Air conditioner indoor and outdoor fans, refrigerator cooling fans, kitchen appliance ventilation fans;
- Industrial: Industrial control cabinet cooling fans, small equipment ventilation fans;
- Electronic Equipment: Server cooling fans, projector cooling fans, etc.
Core Advantages of the Solution: Creating Dual Value for Customers
- Cost Optimization: Integrated architecture + flexible sampling methods reduce BOM costs and hardware R&D investment;
- High Reliability: Multi-condition adaptability + high integration module stability reduces wind turbine operation failures;
- Easy Adaptability: Offline parameter identification + multi-mode control shortens customer product debugging and mass production cycles.
