I've been studying for a while now topics related to power quality issues, such as harmonics caused by non-linear loads and power converters, and I've been working on Active Power Filters, but since I live in developing country sadly all we have is theoretical knowledge, So I appreciate if you add any professional knowledge to those conversation.
- What is the commercial name of an active power filter (if I write that under electronics in Amazon, it doesn't give me any result)
- Same question goes to Unified Power Quality Controller ? (I can't find those in Amazon too)
- What are the main manufacturers of those devices in the world?
- Could you recommend any good readings about this topic to have an idea about the industrial and marketing field
