How do filters affect the efficiency and reliability of AC drives?
AC drives, also known as variable frequency drives (VFDs), are devices that control the speed and torque of electric motors by varying the frequency and voltage of the input power. They are widely used in industrial applications to save energy, improve performance, and reduce wear and tear. However, AC drives also generate harmonics, which are distortions in the current and voltage waveforms that can cause interference, overheating, and damage to the drive and other equipment. To mitigate the harmful effects of harmonics, filters are often installed in the AC drive system. But how do filters affect the efficiency and reliability of AC drives? In this article, we will explain the types, functions, and benefits of filters, as well as some tips on how to select and install them properly.
