rEScontrol, thus indirectly control charging current I
cHG; The Main Function of the second adjuster REG2 controls the output current of charging battle array group 2, thus directly or indirectly control charging current I
cHG.
When control system judges to need charging battle array group 2 pairs of batteries to charge, control system controls equinox switch ENOX and is connected to battery-end BAT, controls by the first adjuster REG1 the residual current I filling BCDR
rEScontrol the charging current of battery, control the current divider of charging battle array group to regulate battery charging current when underloading by the second adjuster REG2; When control system judges to need charging battle array group to power to bus, equinox switch ENOX is connected to bus load end BUS by control system, and the current divider controlling to charge in battle array group by the second adjuster REG2 is to regulate busbar voltage.
Preferably, as shown in Figure 1, the CSB-PCU framework of the present embodiment also comprises boost charge branch road 3, boost charge branch road 3 comprises the first resistance R1, the first switch S 1 and the second resistance R2, be connected between bus load end BUS and battery-end BAT after first resistance R1 and the first switch S 1 serial connection, second resistance R2 and the first resistance R1 be connected in series and the parallel connection of the first switch S 1, the first switch S 1 is connected with control system, and the controlled Systematical control of its switch motion.The Main Function of boost charge branch road 3 is when charging battle array group is connected on bus by equinox switch ENOX, carries out boost charge by boost charge branch road 3 pairs of batteries, to make up battery because the reduction of the energy that produces of self discharge and voltage.
Although the CSB-PCU framework of above-mentioned first embodiment can realize object of the present invention, in space power system, aviation power system and navigation power-supply system, realize the control to power supply, still there is following defect in it:
1. the problem brought of equinox switch ENOX:
