Abstract: A control method of a power factor correction circuit (1) is provided. The first operating frequency of the power factor correction circuit (1) is controlled to less than one-third of the minimum limitation frequency, the first operating frequency is controlled to less than 1-Nth of the first suppression frequency, and the second operating frequency of the power factor correction circuit (1) is controlled to less than 1-Nth of the second suppression frequency. Consequently, at least portion of the operating frequency of the power factor correction circuit (1) is not in the range measured by the machine so as to reduce the value of the noise of the electromagnetic interference.

Abstract: An electronic device (10) and a variable frequency control system using the electronic device (10). The electronic device may comprise: a shielding layer (102), which is inserted between a current outflow terminal (201) of a switching device (20) and a grounding conductor (50); and a conductive elastomer (101), which is used for connecting the current outflow terminal (201) to the shielding layer (102).
