摘要
Abstract
Considering the satellite Power Conditioning Unit (PCU) works in hash environment,a robust design and optimization based on HE-Boost Topology was proposed in battery discharge regulator (BDR).In term of design for circuit,while transconductance control method was used and small-signal model was built,transfer function and parameter was achieved.In term of optimization design and reliability,a robust design was used.Suitable parameter was got from the parameter sweep and vary analysis;the bus voltage of multi-module parallel circuit remained stable,while components parameter were changed within a certain range or components get fail by stress analysis,a worst-case analysis(WCA) and one failure mode simulation.In conclusion,the robust design and optimization was suitable for satellite power circuit,especially for places which need higher requirements for reliability.关键词
