Abstract
An electronically commutated fan has a complex digital control mode compared
to the conventional alternating current fans. Since a serious electromagnetic
compatibility situation occurs in the electronic commutation fan system,
the filter circuit and mechanical design of a fan system are very important.
A digital control strategy for a fan was designed to reduce the component
of the electromagnetic interference filter, therefore the suppression of
conducted and radiated electromagnetic interference will be achieved in
the proposed fan system. Moreover, the proposed fan integrates the mechanical
design to solve the problems of radiated electromagnetic interference.
A single-phase Brushless DC Electric Motor (BLDC) driver is designed and
constructed. Finally, the electromagnetic interference that occurred in
the proposed fan is analyzed and the suppression strategy is provided.
The experiment verification for the electronically commutated fan is presented.
