EC & DC FANS

Technical Solution

The overall controller scheme adopts a topology structure of three-phase rectification, power inverter, and signal control.

The three-phase power supply is rectified by diodes to become a stable DC voltage.

The inverter part formed by six power switching devices is connected with the motor winding.
