Digital sequential shunt regulator for solar power conditioning of engineering test satellite (ETS-V)

A digital sequential shunt regulator (DSSR) is present that regulates the bus voltage of the high-power ETS-V by controlling solar array segments sequentially in an on-off switching manner. To reduce EMI generated from switching surge current, A current-limiting circuit has been designed, and its effectiveness is verified experimentally. Static and dynamic characteristics of the voltage regulation loop are analyzed, and results are in good agreement with experimental results.<<ETX>>
