Because of the many complex subsystem interactions which occur within modern electronic power-processing systems, it is often quite difficult to accurately predict total system performance. A digital computer simulation technique, which can be used to study such composite power-conditioning systems, is applied to a spacecraft direct-energy-transfer power-processing system. The results obtained duplicate actual system performance with considerable accuracy. The validity of the approach and its usefulness in studying various aspects of system performance such as steady-state characteristics and transient responses to severely varying operating conditions are demonstrated experimentally.
