This paper presents a compact RF power inverter implemented with a PCB multi-resonant input filter for driving an electrothermal plasma micro-thruster, mini Pocket Rocket 3.0 (miniPR 3.0). This miniPR 3.0 and its driving electronics are part of an investigation seeking to add micro propulsion systems to low cost CubeSats. The proposed RF power inverter and multi-resonant input filter use only air...
This paper presents the design of a low mass RF power inverter at moderate to high power levels (e.g. tens of watts and above) for weight critical applications such as cubesat plasma thrusters. Our approach for mass reduction includes resonant switching operation at tens of MHz, and the 3D printing of light-weight scaffolds that form air core inductors after plating with a thin layer of copper. Specifically,...
