I was asked a question by a colleague of mine did not know the answer. I'm sure someone here can help.
He is purchasing a 4KV AC/DC converter (not sure what for) and the vendor quoted him a 24 pulse system. This threw up a red flag because naturally the 24 pulse system is much more expensive than 6 pulse. His question was basically what is the difference a 24 pulse and 6 pulse converter.
In my research I found that using a 24 pulse system cancels out all of the lower order harmonics (2-22). I also saw that this is advantagous in HVDC systems. This is what I don't understand. Why would eliminated lower order harmonics matter more in a high voltage system?
