Improved model of a partial shunt regulator for spacecraft

摘要

The partial shunt regulator (PSR), which is a typical spacecraftnpower regulator, is modeled. To realize a simple structure, the voltagensource of the PSR controller is identical to the output voltage of thenPSR. However, the small-signal model structure of the PSR is veryncomplex, because the PSR has a main feedback control loop as well as twonadditional coupled loops. The complex structure of model is simplifiednto a more meaningful structure, which has only one main feedback loop.nThe proposed PSR structure is verified by comparing the analysis of thenmodel with SPICE simulation of the PSR circuit
