This article proposes a solar array regulation technique for a high-voltage satellite power bus. The regulation method combines on–off control at low frequency, i.e., kHz range, of highly efficient isolated and unregulated dc–dc converters operating at high frequency, i.e., hundreds of kHz. Although this technique can adopt different implementations, this article deals with a hysteretic voltage control loop at low frequency, also known sequential switching shunt regulator (S3R), and unregulated, isolated, current-fed, zero-voltage, and zero-current push–pull dc–dc converters. Design guidelines and experimental validation are provided.
