I am working on a project that I am in need of a Pulse Generator that can pulse with a small load of approx 50ma and a voltage of 1.5 - 2.5kv. Also I am wanting to design a HV switch.. same voltage range. Any Suggestions or schematics on the net? Since I am on a Roll asking for information. Without going to an AC circuit how can I step up DC 12v - 1.5 - 2kv?
