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.
