June 2019, Colorado Power Electronics was mentioned in a press release by NASA:
“Colorado Power Electronics Inc. of Fort Collins, Colorado, will partner with Glenn to mature power processing unit technology that extends the operating range of Hall thrusters, which are primarily used on Earth-orbiting satellites and can also be used for deep space missions. By integrating their technology with NASA and commercial Hall thrusters, the company expects to provide a propulsion system that can significantly increase mission payload or extend mission durations.”
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.
