| The impact of the clamp capacitor design, the dynamic specifications and the EMI filter design on the power stage design of a 28V 50W Forward with Active Clamp converter for space applications is analyzed along this paper. Clamp capacitor is designed by considering the ECSS standards limitations for the semiconductors and saturation of the magnetic components, and considering the influence of the resonance between this capacitance and the magnetizing inductance on the input impedance of the converter. Dynamic specifications influence are analyzed. Additionally, the EMI filter design process is described. Singlestage and Multi-stage approaches are proposed. All these features make an increase of 2:4W losses and 1:6 higher area of the converter, compared with a preliminary design of the power stage, before considering these aspects.Power Distribution Module for Space Application. Two architectures and, among them, four well known isolated (Half-Bridge, Push-Pull, Forward with Active Clamp (FWAC) and Flyback with Active Clamp (FLAC)) and nonisolated (Buck and Synchronous Buck) DC/DC topologies are analyzed and compared in terms of efficiency and size, meanwhile taking care of the cost, design time, reliability and flexibility of the whole system. In order to validate presented theoretical results, laboratory prototype for FWAC topology for 28V, 1:75A converter is built and measured. The prototype?s minimal 92:3% and maximal 93:2% efficiency match pretty good with expected 92:9% and 94%, respectively. | |
