The invention provides a storage battery charging device with four switch tubes for a satellite and a control method of the storage battery charging device. The charging device comprises an input end VIN, a first capacitor, switch tubes Q1, Q2, Q3 and Q4, an inductor L1, a second capacitor and an output end VOUT. A BUCK mode and a BOOST mode are switched through on-off of the switching tubes Q1, Q2, Q3 and Q4; the four-switch conversion circuit adopted by the invention can realize boost and buck, the defect that the conventional sailboard can only be smaller than or equal to the total voltage of the storage battery is overcome, the defect that the output voltage of the conventional sailboard cannot be larger than the voltage of the storage battery is overcome, energy waste is also avoided, meanwhile, the sailboard does not need to bear redundant energy, and the cost is reduced. And the service life of the sailboard is prolonged.

    本发明提出一种卫星用四开关管的蓄电池充电装置及其控制方法,所述充电装置包括输入端VIN,第一电容,开关管Q1、Q2、Q3、Q4,电感L1,第二电容和输出端VOUT;通过开关管Q1、Q2、Q3、Q4的开通关断切换BUCK模式和BOOST模式;本发明采用的四开关转换电路能够实现升压与降压,改进以往帆板只能小于或等于蓄电池的总电压的缺点,解决了原先的帆板输出电压不能大于蓄电池电压的弊端,也避免了能源的浪费,同时帆板不必承受多余的能量,使帆板使用寿命增加。
