Abstract
Ion pumps rely on high-voltage power supplies with low output ripple to generate ultra-high vacuum. This paper presents a 2 to 7 kV DC power supply with less than 10 Vpp voltage ripple designed for such applications. The circuit utilizes high-frequency inverters, planar PCB transformers, Dickson voltage multipliers, and ripple cancellation techniques to achieve a compact, low-ripple high-voltage source.
