Maintaining and Troubleshooting Variable Frequency Drives

VFDs have become standard devices in today's electrical systems. Selecting the correct type of VFD for each motor application, installing and maintaining it are all required knowledge for electrical design engineers, operating engineers, and service mechanics. With so many types of VFDs available for both HVAC and industrial applications, knowledge of how they work is necessary for choosing the correct VFD and keeping it operating successfully. This book provides an understanding of industrial electronics, VFDs, and motors, and provides VFD selection and application guidelines. It even includes a comprehensive troubleshooting guide with procedures for correcting start-up and intermittent problems.
