“…Different division methods of hysteresis bands are shown in Fig. 2 [14, 18, 19]. It is more difficult for two sections to influence each other for hysteresis bands with dead‐zone, whereas with overlapping S3R can expand hysteresis bands to restrain the failure operation of the regulating section caused by noises.…”

“…Adding hysteresis comparator control section and power stage together, then we can obtain the transconductance G = I SA / V hl_m . Note that G is the transconductance corresponding to V hl [14], not V hh in [22] or total approximation in [18, 19]. Because that the change of v MEA is V hl in normal mode.…”

“…In earlier studies, relationships of basic circuit parameters were given in [16], and the steady state and small signal models of power stage of the new conditioner like S3R were proposed [17]. Then, system model of S4R is analysed in [18, 19], in which a simple linearisation of non‐linear transconductances is obtained. The control loop design of S4R is also given based on this system model in [20].…”

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.
