Two first generation power conversion systems which utilize multiple AMTEC cells (based on PX-3 or PX-5 series cell designs) have been studied. The experimental setup and results are discussed. The experiments demonstrated the feasibility of AMTEC cells operated in a series connected circuit, while surfacing several key issues which must be addressed for successful future power systems. The 8-cell converter demonstrated an efficiency of 11.12% and a maximum power of 28.4  W e at a hot end temperature of 1123 K and condenser temperature of 553 K. The 4-cell converter demonstrated an efficiency of 10.5% and a maximum power of 12.54  W e at a heater input of 120  W e and a condenser temperature of 535 K.
