The harmonic current generated by the rectifier circuit will cause voltage waveform distortion, which affects many instruments, especially more obviously under weak power supply. This interference will not change depending on the distance between the equipment and the inverter. The input and output cables of the inverter will generate electromagnetic radiation, and high-frequency equipment close to the inverter is prone to interference.
Harmonic interference
The harmonic current generated by the rectification circuit will cause voltage waveform distortion, which affects many instruments, especially more obviously under weak power supply. This interference will not change with the distance between the equipment and the inverter.
Radio frequency radiation interference
The input and output cables of the frequency converter will generate electromagnetic radiation, and high-frequency equipment near the frequency converter is prone to interference.
