Variable Frequency Drive: Installation & Troubleshooting!

Very basics of how IGBT works. Just enough for a service tech to understand.

thx

good book

It became necessary for me to construct a device to twist larger steel rods as well as make scrolls as a business owner.Hence the need to control the speed and rotation of an ac motor correctly and exactly.I did some reading and got some information. But nothing gave me the background knowledge, insight and confidence that this very well written and illustrated book did.I am already testing my devise fully aware of what I am doing and why I am getting the outcomes I am getting.If you are interested in VFDs in any way; get this book.Get it even if you only just want to know!
