Variable frequency series resonance test equipment is used to achieve variable frequency by changing the power supply frequency.The specific implementation method is as follows:
 

 

　　Frequency Converter:Use a frequency converter to convert the power frequency to the desired frequency.A frequency converter is an electronic device that can adjust the input power frequency and output the desired frequency.Frequency changes can be achieved by adjusting the parameters of the frequency converter.

　　Resonant Circuit:Connect the frequency converter's output frequency to the resonant circuit.A resonant circuit is a circuit that can amplify and produce a resonance effect for a specific input signal frequency.By adjusting the parameters of the resonant circuit,the resonance frequency can be matched with the frequency outputted by the frequency converter.

　　Test Equipment:Connect the test equipment to the output of the resonant circuit.The test equipment can be an electric motor,transformer,etc.,used for actual testing.By changing the output frequency of the frequency converter,the operating frequency of the test equipment can be adjusted.

　　In summary,the frequency converter is used to convert the power frequency to the desired frequency,which is then inputted into the resonant circuit.By adjusting the parameters of the resonant circuit,a resonance effect is achieved,and the output is connected to the test equipment for experimentation.
