Abstract
A variable frequency converter and an adjusting method for the same are provided in the present application. The variable frequency converter operates in a variable frequency mode, and comprises a power stage circuit module and a variable frequency signal stage circuit module which are connected to form a closed-loop circuit system. The variable frequency converter further comprises an adjusting unit outputting a continuous interfering signal and loading the continuous interfering signal into the variable frequency signal stage circuit module so as to cause operating frequency of the power stage circuit module controlled by the variable frequency signal stage circuit module to change continuously. In the present application, in the variable frequency converter, the EMI peak value is decreased.
