Outline
The High Voltage Power Supplies (HVPS) are used for Particle Accelerators, Broadcast Transmitters, Defense Research as well as Radio Frequency Amplifiers/Oscillators , covers the potential use in physics experiments , Industrial and medical applications.
Pulse Step Modulation based HVPS was developed for ion dump in accelerator beams. The HVPS provide required voltage with regulation, resolution and dynamics in µS order for extended pulse duration. Additionally it can also support voltage modulation up to 1 kHz with programmable rise/fall time. Fast protection action against short circuit is integral feature.
