Title: High Voltage Adder
Post by bki on Apr 10^th, 2015, 2:59am

I like to sum three high DC voltages (50V each) up.
How can i sum those high voltages to 150V?

My advisor said that i can not do it by OpAmp adder circuit, because the OpAmp itself then needs a supply voltage of 150V which makes it useless?! It that really true?

use voltage charge pump... search for Dickson charge pump as a start.
