Description

technical field [0001] The invention relates to a power supply system, in particular to an intelligent power building block and a distributed space power supply system based on the intelligent power building block. Background technique [0002] The space power supply adopts centralized control and modular design. There are mainly the following development methods: [0003] (1) Fully adjustable bus architecture based on S3R technology [0004] The S3R architecture is widely used in the development of power controllers because of its simplicity, reliability and high efficiency. The DC power supply system is composed of a shunt controller SR, a battery charge controller BCR and a battery discharge controller BDR, and the three are jointly controlled by the main error amplifier MEA. S3R power regulation technology mainly regulates and controls the busbar through the error op-amp interval, and controls the shunt regulation unit, charging unit and discharging unit respectively t...
