The application of micro power system is prevailing. This talk would introduce the concept, design and demonstration of micro-thermophotovoltaic (micro-TPV) power system. However, the overall efficiency of micro-TPV is strongly associated with radiant efficiency and quantum efficiency. How to improve the overall efficiency of micro-TPV power system during the miniaturization process is a quintessential question to researchers. The talk would point out the inherent deficiency of a small combustion system and propose some promising strategies to overcome these defaults. In addition, the concept and demonstration of pulsed plasma thruster (PPT) and vacuum cathode arc thruster (VCA) will be mentioned eventually, and both thrusters are appropriate for the electric propulsion of CubeSat.
