На фиг.1 представлена принципиальная электрическая схема автономного источника электропитания с резервным аккумулятором. Figure 1 shows a schematic diagram of an autonomous power supply with a backup battery.
На фиг.2 представлена временная диаграмма напряжений управления транзисторов. Figure 2 shows a timing diagram of the control voltages of the transistors.
Автономный источник электропитания с резервным аккумулятором содержит аккумуляторы 1 , 2, повышающий преобразователь постоянного напряжения в постоянное 3, нагрузку 4, конденсатор 5, транзисторы 6 - 9, диоды 10 - 13 и систему управления 14, причём один аккумулятор 1, через соединённые последовательно транзистор 6 и диод 10, подключен параллельно входу повышающего преобразователя постоянного напряжения в постоянное 3, к выходу которого, через соединённые последовательно нагрузку 4, вторые транзистор 7 и диод 11, параллельно подключен конденсатор 5, параллельно которому, через соединённые последовательно третьи транзистор 8 диод 12 подключен первый аккумулятор 1, также, параллельно конденсатору 5, через четвёртые транзистор 9 и диод 13 подключен второй аккумулятор 2, а система управления 14 соединена с транзисторами 6 - 9. An autonomous power supply with a backup battery contains batteries 1, 2, a DC-to-DC boost converter 3, a load 4, a capacitor 5, transistors 6 - 9, diodes 10 - 13 and a control system 14, with one battery 1, through transistors 6 connected in series and diode 10, connected in parallel to the input of the DC-to-DC boost converter 3, to the output of which, through load 4 connected in series, the second transistor 7 and diode 11, capacitor 5 is connected in parallel, in parallel to which, through the third transistor 8 connected in series, diode 12 is connected to the first battery 1 is also parallel to capacitor 5, a second battery 2 is connected through the fourth transistor 9 and diode 13, and the control system 14 is connected to transistors 6 - 9.
Автономный источник электропитания с резервным аккумулятором работает следующим образом. Открываются одновременно транзисторы 6 и 7, в результате чего, постоянное напряжение аккумулятора 1 подаётся на вход повышающего преобразователя постоянного напряжения в постоянное 3, с выхода которого, повышенное постоянное напряжение, через нагрузку 4 подаётся на конденсатор 5, который заряжается и
транзисторы 6 и 7 закрываются. Затем, открывается транзистор 8 и конденсатор 5 разряжается на аккумулятор 1, подзаряжая его. Система управления 14 контролирует состояние аккумулятора 2 и при необходимости, через транзистор 9 и диод 13 подзаряжает его от конденсатора 5. Таким образом, при закрытых транзисторах 6 и 7, открываются транзисторы 8, или 9. An autonomous power supply with a backup battery works as follows. Transistors 6 and 7 open simultaneously, as a result of which the constant voltage of the battery 1 is supplied to the input of the DC-to-DC boost converter 3, from the output of which the increased DC voltage is supplied through load 4 to capacitor 5, which is charged and transistors 6 and 7 close. Then, transistor 8 opens and capacitor 5 discharges to battery 1, recharging it. The control system 14 monitors the condition of the battery 2 and, if necessary, through transistor 9 and diode 13, recharges it from capacitor 5. Thus, when transistors 6 and 7 are closed, transistors 8 or 9 open.
