During the equipment debugging process, it is often encountered that the frequency converter interference causes the instrument signal to jump wildly. Harmonic interference is mainly caused by the harmonic current generated by the rectification circuit, which will cause the voltage waveform to distort and affect the instrument signal.
Common interference phenomena
During the equipment debugging process, it is often encountered that the frequency converter interference causes the instrument signal to jump randomly.
Causes of harmonic interference
Harmonic interference is mainly caused by the harmonic current generated by the rectifier circuit, which will cause distortion of the voltage waveform and affect the instrument signal.
Radio frequency radiation interference
There is radio frequency radiation interference between the output cable and the input cable of the variable frequency converter, which will affect other electronic devices when they are close.
Solution method
The methods to solve the interference of inverters include adopting single-point grounding, shielding signal lines, isolating power supply and other measures.
