Interference in inverter applications and its suppression
The frequency converter is applied to various fields of industrial control with its energy saving, energy saving, reliability and high efficiency, but it also brings some interference problems. The power supply and power equipment on the site will affect the inverter. The higher harmonics generated by the inverter will also interfere with the operation of the surrounding equipment. There are three main types of interference generated by the inverter: interference to electronic equipment, interference to communication equipment, and interference to radios. The interference generated by electronic devices such as computers and automatic control devices is mainly induced interference; the interference generated to communication devices and radios is radiation interference. If the interference problem of the inverter is not solved well, not only can the system not operate reliably, but also affect the normal operation of other electronic and electrical equipment.
