This paper 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 paper 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.
