The application of MOS transistor in frequency conversion fan, which is an innovative product of home appliance industry in recent years, is realized through built-in motor and controller, the wind speed can be adjusted automatically according to environmental temperature, humidity and other conditions to achieve energy-saving effect. Users can also use mobile apps and other means to control, to achieve a more intelligent use of the experience. Frequency conversion fans are widely used in industrial production and family life and other fields.
Its working principle is the frequency converter through the input frequency, voltage to control the motor speed, and then drive the fan blade rotation to produce airflow. The utility model has the advantages of high flexibility, high energy efficiency, stable air volume, low noise, etc. .
Through its internal structure we know that the fan is also using brushless motor, three-phase inverter full-bridge circuit, composed of six n-channel MOS transistor three-phase full-bridge. The controller completes the switch by controlling the on-off of 6 MOS transistors. According to different scenarios, the controller can save energy and improve the service life of the fan.
The field effect tube of Ling Xin micro is widely used in the intelligent frequency conversion electric fan, and various models can be provided.
The recommended package is TO-252/TO-263.
The product advantages:
In VDS withstand voltage, can guarantee withstand voltage performance;
