Drive systems that require variable-speed motor rotation are powered by a AC/DC/AC frequency converter. Such an inverter is a nonlinear load that generates disturbances in the form of current harmonics. One way to reduce this negative effect in the power line is to use passive filtering. The article presents types of filtering and conducts a study and analysis of the operation of a low-pass filter designed for this type of drive system.

摘要

Drive systems that require variable-speed motor rotation are powered by a AC/DC/AC frequency converter. Such an inverter is a nonlinear load that generates disturbances in the form of current harmonics. One way to reduce this negative effect in the power line is to use passive filtering. The article presents types of filtering and conducts a study and analysis of the operation of a low-pass filter designed for this type of drive system.
