Digital Isolation for AC Voltage Motor Drives

Digital Isolation for AC Voltage Motor Drives


Isolation is an integral part of ac voltage motor drives.
There are several methods of providing electrical isolationā€”
primarily, optocouplers and digital isolators are used. The
use of digital isolators provides several benefits as compared
to traditional optocouplersā€”some of which include
reduction in cost, component count, and improved
reliability. This article will compare methods of isolation in a
traditional motor controller design to highlight the benefits
of digital isolators.
