Circuit delivers high voltage swing from lower supplies: 12/12/2002 EDN - Design Ideas / The need for higher voltage swings in applications such as test-and-measurement instruments is constantly increasing, but the power supplies impose limitations on the operational amplifier rails make the high-voltage need a challenge for designers. How do you deliver high-voltage swings to a load without increasing the voltage levels of the power supplies of the operational amplifier?
COCKCROFT and WALTON VOLTAGE MULTIPLIERS: Here are some applications of the Cockroft-Walton voltage doubler circuit for generating high voltages from a low voltage AC source. The circuit is quite practical for generating thousands of volts (or more) or just a few volts at high current.
