Sequential switching shunt regulator (S3R) has been widely used in satellites for its simple structure and high reliability. Double section functioning, which has two sections operating simultaneously, is the other operating mode of S3R beside the normal mode. It is inevitable and can lead to larger bus voltage ripple, less controllability and higher switching losses. A detailed analysis based on the double section functioning process description is given on the boundary load current, the main bus voltage ripple and the switching frequency. Considering the influence of double section functioning, a new method of control loop design of S3R is proposed based on the small single mathematical model. A 4.5 kW S3R prototype is built to verify the control loop design, and the load region of double section functioning can be limited as designed.

Electric power generation and conditioning have experienced revolutionary development over the past two decades. Furthermore, new materials such as high energy magnets and high temperature superconductors are either available or on the horizon. Our work is based on the premise that new technologies are an important driver of new power system concepts and architectures. This observation is borne out by the historical evolution of power systems both in terrestrial and aerospace applications. space power systems by using several new technologies. This paper will introduce new approaches to designing

“…The S3R concept has the following advantages: truly modular design; "small" bus filter required; only one module switching at a given time; excellent dynamic response to large load changes; bus voltage ripple is small; flexible design with inherent growth potential and so on [2]. Nowadays, this technology is widely used in the space market.…”

Considering the space Power Conditioning Unit (PCU) needs high reliable design, especially for it works in harsh environment, a robust design and optimal method is proposed. Firstly the mathematical model of sequential switching shunt regulator(S3R) is shown to be suitable for regulated bus power systems. Secondly, optimize the bus capacitor parameter by the parameter sweep analysis. Thirdly, when all the components change simultaneously in the worst case, the performance of the S3R circuit meets the design requirements and the shunt components meet the derating requirements in the monte carlo analysis and stress analysis. Finally, simulate two failure modes: the load changes in pulse mode and the current supply of the second-stage solar array is zero, the simulation results show that the output of the bus voltage is stable and ripples in the specified range.
