a new optimum topology dc-todc switching converter is extended to provide bidirectional current flow. The resulting two-quadrant converter can be employed to eliminate the discontinuous curent mode in normal unidirectional applications, but is especially suited for spacecraft battery conditioning as a charge-discharge regulator in place of the conventional separate converters. Implementation of the...
Over the last two years, the CERT-DERA has developed for the ESTEC a general model for the analysis and synthesis of power regulators (1),(2). A numerical programme was written to show the validity of the model. As the results obtained were conclusive, the ESTEC decided to develop software for the Computer Aided Design of these power regulators. The basic development hypotheses were the adaptation...
This paper presents a discussion of the power processor for an electrical power system for a 25 kW Power Module that could support the Space Shuttle program during the 1980's and 1990's, and which could be a stepping stone to future large space power systems. Trades that led to selection of a microprocessor controlled power processor are briefly discussed. Emphasis is given to the power processing...
