PCB board requirementsGeneral:
- It is powered by 5V, 2A, USB-B connector. There is a manual switch ON/OFF on the board.
- It charges a ceramic high voltage capacitor (HVC) of 100uF up to 1kV Target Voltage.
- A discharge is automatically triggered upon the charge on HVC reaching a Target Voltage.
- Discharge occurs through a thyristor, alike the Vishay VS-ST380CH06C1, into a superconductor.
- When the power switch is switched OFF, the HVC discharges slowly and safely in a dummy resistor or light emitter over <10sec period of time.
- Size: PCB volume is <2dm3.
There are following indicators:
- A digital display of the voltage across HVC, precision <20V.
- A red diode indicating “charging” state for HVC.
- An orange diode indicating the current charge across HVC being >50V.
- A green diode indicating “charged” state for HVC at Target Voltage.
There are following manual controls, that can be realized via some variable capacitor or resistor or switch, adjusted using a screwdriver or other means:
- The charging speed can be regulated in range 1W-10W, in ~1W steps.
- The Target Voltage of HVC can be set between 300V and 1kV with precision ~50V.
ContextThe built PCB is intended to be used for some private R&D project to build a demonstrator for a part in a space-propulsion system. If successfully validated, the PCB would overgo a high-end respin with some microcontrollers onboard, to allow it to be managed on a satellite.
