I need a module that can take a DC voltage of 2V - 12V continuously as its input and produce atleast 2KV DC continuously as its output. I've come across high voltage generator boost modules but they produce output in pulse (discontinuous.) What I want to know is do such modules exist that can continuously produce thousands of volts from low input voltage? If yes what are they usually called as?

I'm aware of high voltage bench power supplies that can continuously produce thousands of volts. But I don't want that. I just want a smaller device such as a module.

Application:

I want to use the module to power a parallel plates electrostatic device.

  • Digikey has many *DC to DC converters*. – Mattman944 Oct 23 '20 at 10:16

    Q1: What power / current output? | Q2: Knowing the application is liable to help greatly. – Russell McMahon Oct 23 '20 at 11:51
  • @RussellMcMahon Current output is not a requirement for my application. Only high voltage is a requirement. About the application, I've updated my answer and mentioned the application. – Somanna Oct 23 '20 at 11:59

    Current output *is* a requirement. Even electrostatics use current - it may be small (1µA or less) but you'll have zero volts with zero current. – rdtsc Oct 23 '20 at 12:01
  • @rdtsc Yes your are correct. A small current about 1µA - 100mA is enough for my application. – Somanna Oct 23 '20 at 12:04

    At 2kV DC 100mA is going to be a lot more expensive than 1µA – bobflux Oct 23 '20 at 12:29

    I do not know whether you are aware, but the basic premise of a boost converter requires switching operation, so nothing you find will be perfectly smooth unless you search for a different method to boost the DC signal. However, faster switching will of course give you a smoother result. – kanoo Oct 23 '20 at 13:02

    2kV·1µA=2mW. 2kV·100mA = 200W. That's a hell of a difference. – Janka Oct 23 '20 at 13:32

    Can also consider AC - HV transformer - voltage multiplier stages. The DC coming out of that will still have ripple, but not a lot. Add an LRC filter after it, voila. – rdtsc Oct 23 '20 at 13:54

    The only thing close that I was able to find was 14-18Vin to 2000vout and 20mA output. So 40W. I don't know of any modules that output high voltage with that much current. – bunker89320 Oct 23 '20 at 16:30
