Abstract :
An improved Mapham inverter for high-frequency space power conversion is presented. The inverter system employs a starting commutator to facilitate the startup of the conventional inverter under full-load conditions. The load conditions that would cause startup commutation failure are established, and the behavior of the improved inverter is studied. Simulation results verify the predicted startup performance. A generalized steady-state analysis of the inverter is presented, and performance curves are derived
