The application of electric propulsion systems in CubeSats can increase lifetime and diversity of possible missions, with improved capabilities in orbital maneuvers. In this work, a control and power electronics circuit for a gas-fed pulsed plasma thruster (GFPPT) was developed, constructed and tested, considering restrictions in size, weight, and power availability of a CubeSat. This proof of concept made use of 3D printing technology for rapid prototyping, and its initial testing was done in an atmospheric environment.
