Abstract Sequential switch series shunt regulator(S4R) is used as space photovoltaic(PV) 20kW power conditioning unit(PCU). In order to improve high power density, a reasonable solution is reducing the filter healing capacitor array size and weight. Sigma-delta control strategy is proposed to gate the shunt switch by overclocking at the same efficiency with the hysteretic control. Modeling, loop design and system stable of sigma-delta control is analyzed in this paper. A better dynamic performance and power density ratio than the Bang-Bang control is proved by simulation and experiment.

Key words： Sequential switch series shunt regulator(S4R) sigma-delta control strategy overclocking power density modeling stable
