Mid-February 2014, Colorado Power Electronics successfully designed, tested and shipped a 100kV power supply. For its output, the unit is a surprisingly-small form factor.
Utilizing ceramic capacitor/diode multipliers combined with a high-turn output inductor and toroidal capacitor, this unit is both impressive in performance and appearance.
Control of this unit includes an easy-to-read LCD display combined with an embedded push-button keypad. Output voltage and current are monitored and displayed on a live graph on the display.
Even the main contactor which shorts the output of the unit is custom-built and verified to function up to the maximum voltage.
