A Hybrid Sequential Switching Shunt Regulator (HS3R) for Satellites
Keywords:
About Hybrid regulator, regulated spacecraft power system, satellite regulation system.Abstract
This document presents a sequential switching
shunt regulator (S3R) operating with a digital shunt regulator,
as hybrid configuration (HS3R) for solar array regulators. This
approach describes the principles of this topology as part of a
power subsystem of a lunar exploration satellite. The proposed
technique is especially useful to reduce the high solar array
parasitic capacitance that shows the actual satellites. The
response of the HS3R is studied against large transient load
changes using a hybrid configuration to reduce the losses. The
results show the dynamic response of the system during each
test.
