| Abstract: | An electronically commutated fan has a complex digital control mode compare to the conventional alternating current fans. Since a serious electromagnetic compatibility situation was produced in the electronic commutation fan system, the filter circuit of a fan system and its mechanical design was significantly important. Because the digital control strategy for an electronically commutated fan was used to reduce the component of the EMI filter so the suppression of conducted and radiated electromagnetic interference will be discussed in this fan system. Moreover, the fan system can be combined with the mechanical design for getting over a series of issues of radiated electromagnetic interference. Thus, fig.1 reveals that a single-phase BLDC motor driver schematic diagram. Eventually, a cause that electromagnetic interference was produced from the electronically commutated fan will be analyzed and its suppression strategy also provided in this paper. The experiment verification for the electronically commutated fan will be made available to the public. |
