There are various applications of high voltage for scientific experiments onboard satellites, deep space missions, space shuttle or ISS.
Every application requires dedicated solutions in terms of voltage, current, functionality, safety and protection.
Also high voltage, high frequency supplies are available e.g. for levitation and melting as well as for actuators.
A special domain is fast switching of high voltage for radar and laser modulators.
