In this paper, a simulation prototype of a high-power radioisotope thermoelectric generator (RTG) simulation prototype based on skutterudite is designed. By replacing the isotope heat source with an electrically heated heat source, its output power is 40 W under the condition of 1600 W electric power heating, and the thermoelectric conversion efficiency can reach 2.5%. The simulation prototype contains a total of 8 thermoelectric modules, and each module contains 16 pairs of thermoelectric materials. Its maximum theoretical output power can reach 66 W under the temperature of 550 °C. This research provides a leading guide and reference point for the temperature difference structure of RTGs at the hundred watt level.
