Abstract

MPPT (Maximum power point tracking) is applied in order to reduce the area of solar panels on spacecrafts, improving the power density and reducing the cost. S3MPR (Sequential switching shunt maximum power regulator) combines S3R (sequential switching shunt regulator) power topology and MPPT control strategy and is suitable for high-voltage high-power platform with solar arrays in parallel. In this paper, we propose a new analog MPPT control method (the variable observation method) and use the S3MPR as the power topology. In this new designed method, the dynamic MPPT reference is generated by observing the logic relationship between derivatives of output voltage and power. Finally, a whole analog MPPT control circuit is designed to satisfy the requirements for space applications. The Saber simulation platform is built and simulation results confirm the principles.
