СУЩНОСТЬ ИЗОБРЕТЕНИЯSUMMARY OF THE INVENTION

Техническим результатом изобретения является упрощение схемы при одновременном обеспечении требуемой мощности для зарядки в отсутствии яркого света. Изобретение обеспечивает возможность начинать и заканчивать подзарядку аккумулятора зарядного устройства в щадящем режиме, а зарядку аккумулятора мобильного телефона осуществлять как на солнечном свету, так и в полной темноте, обеспечивает одностороннюю подачу электроэнергии от фотоэлектрического преобразователя ФЭП к аккумуляторной батарее.The technical result of the invention is to simplify the circuit while providing the required power for charging in the absence of bright light. The invention provides the ability to start and end charging the battery of the charger in a gentle mode, and to charge the battery of a mobile phone both in sunlight and in total darkness, provides one-way supply electricity from the photovoltaic converter of the solar cell to the battery.

Технический результат достигается за счет того, что автономный источник напряжения содержит фотоэлектрический преобразователь (ФЭП), соединенный с аккумуляторной батареей через диодно-конденсаторный блок, при этом диодно- конденсаторный блок выполнен из конденсатора, включенного параллельно ФЭП и двух быстродействующих диодов шоттки, обеспечивающих отсутствие обратной связи, один из которых включен последовательно между ФЭП и точкой подключения положительного вывода конденсатора, а второй - между этой же точкой (конденсатором) и аккумуляторной батареей со стороны ее положительного вывода.The technical result is achieved due to the fact that the stand-alone voltage source contains a photoelectric converter (PEC) connected to the battery through a diode-capacitor block, while the diode-capacitor block is made of a capacitor connected in parallel to the PEC and two high-speed Schottky diodes, ensuring the absence of reverse communication, one of which is connected in series between the photomultiplier and the connection point of the positive terminal of the capacitor, and the second - between the same point (capacitor) and acc mulyatornoy battery from its positive terminal.

ПРИМЕР РЕАЛИЗАЦИИ ИЗОБРЕТЕНИЯ Автономный источник напряжения (фиг. 1) содержит фотоэлектрический преобразователь (ФЭП) 1, соединенный с аккумуляторной батареей 2 через диодно-конденсаторный блок, состоящий из конденсатора 3, включенного параллельно ФЭП 1, и двух быстродействующих диодов 4 и 5 шоттки, первый из которых включен между ФЭП' 1 и конденсатором 3, а второй - между конденсатором 3 и аккумуляторной батареей 2 со стороны ее положительного вывода. Параллельно аккумуляторной батарее 2 включен светодиод 6 через выключатель 7. Между аккумуляторной батареей 2 и разъемом положительного вывода напряжения может быть включен диод шоттки 8 (фиг. 2). Также автономный источник напряжения может содержать повышающий регулятор 9 напряжения (фиг. 4) для достаточного зарядного напряжения и тока для подачи на аккумуляторную батарею 2 в случае применения ФЭП с низким выходным напряжением, недостаточным для качественной зарядки аккумуляторной батареи.EXAMPLE OF IMPLEMENTATION OF THE INVENTION A stand-alone voltage source (Fig. 1) contains a photoelectric converter (PEC) 1 connected to the battery 2 through a diode-capacitor block, consisting of a capacitor 3 connected in parallel to the photomultiplier tube 1, and two high-speed Schottky diodes 4 and 5, the first of which is connected between the photomultiplier ' 1 and capacitor 3, and the second between the capacitor 3 and the battery 2 from the side of its positive terminal. In parallel with the battery 2, the LED 6 is turned on via the switch 7. Between the battery 2 and the connector for the positive voltage output, the Schottky diode 8 can be turned on (Fig. 2). Also, an autonomous voltage source may contain a step-up voltage regulator 9 (Fig. 4) for sufficient charging voltage and current for supplying to the battery 2 in the case of applying a photomultiplier with a low output voltage insufficient for high-quality charging of the battery.

После начала поступления подачи зарядного тока от ФЭП 1 сначала заряжается конденсатор 3 и далее аккумуляторная батареяAfter the start of the supply of the charging current from the photomultiplier 1, the capacitor 3 is first charged and then the battery

2. После прекращения поступления зарядного тока от ФЭП 1 начинает разряжаться конденсатор 3 и отдавать свою емкость через диод 5 на аккумуляторную батарею 2, т.е. выполняет роль промежуточного емкостного буфера с односторонней связью. Диод 4 обеспечивает отсутствие обратной связи между конденсатором 3 и2. After the flow of charging current from the solar cell 1 ceases, the capacitor 3 starts to discharge and transfer its capacity through the diode 5 to the battery 2, i.e. acts as an intermediate capacitive buffer with one-way communication. Diode 4 ensures the absence of feedback between the capacitor 3 and

ФЭП 1, а диод 5 обеспечивает отсутствие обратной связи и разряд аккумуляторной батареи 2 через конденсатор 3.FEP 1, and diode 5 ensures the absence of feedback and discharge of the battery 2 through the capacitor 3.

ФЭП 1 в предлагаемом зарядном устройстве рассчитан на рабочее напряжение 6,5 вольт и ток не менее 100 мА при условии мощности солнечного освещения не менее 800 вт/кв.м.FEP 1 in the proposed charger is designed for an operating voltage of 6.5 volts and a current of at least 100 mA, provided that the solar power is at least 800 W / sq.m.

Устройство компактно, имеет малый вес и размеры его не превышают 135x65x22 мм.The device is compact, has a low weight and its dimensions do not exceed 135x65x22 mm.

Функционально для зарядки любых мобильных телефонов, как на солнечном свету, так и в полной темноте. Используемые аккумуляторы стандартного типа никель кадмиевые или никельметаллгидридные - тип AAA и достаточно дешевые.Functional for charging any mobile phone, both in sunlight and in total darkness. Used batteries of the standard type are nickel-cadmium or nickel-metal hydride - type AAA and fairly cheap.

При зарядке от описанного устройства мобильных телефонов не важно, заряжены ли полностью аккумуляторы в зарядном устройстве или нет, т.к. даже их минимальное напряжение и мощность выше таких же характеристик аккумуляторов в мобильном телефоне.When charging mobile phones from the described device, it does not matter if the batteries in the charger are fully charged or not, because even their minimum voltage and power are higher than the same characteristics of batteries in a mobile phone.

Использование в цепи зарядки между ФЭП 1 и аккумуляторной батареей 2 диодно-конденсаторного блока позволяет существенно повысить срок службы аккумулятора, а в итоге и всего изделия в целом.The use of a diode-capacitor unit in the charging circuit between the photomultiplier tube 1 and the battery 2 makes it possible to significantly increase the battery life, and, as a result, the entire product as a whole.

Напряжение, выдаваемое ФЭП 1, через диодно- конденсаторный блок поступает на аккумуляторную батарею 2 и не превышает максимально допустимое напряжение, необходимое для зарядки, т.е. аккумулятор невозможно перезарядить, что также существенно сказывается на сроке его службы.The voltage generated by the photomultiplier tube 1, through the diode-capacitor block, is supplied to the battery 2 and does not exceed the maximum allowable voltage required for charging, i.e. the battery cannot be recharged, which also significantly affects its service life.

Использование в зарядном устройстве дополнительно светодиода 6 (фиг. 3) помогает для подсветки при подключении мобильного телефона в темноте, а также данную функцию можно с успехом использовать как локальную подсветку и в светосигнальных целях.Using the additional LED 6 in the charger (Fig. 3) helps to illuminate when a mobile phone is connected in the dark, and this function can also be successfully used as a local backlight and for signaling purposes.

При использовании в зарядном устройстве низковольтных ФЭП 1 и с низким кпд применяется повышающий регулятор 9 напряжения для обеспечения достаточного зарядного напряжения и тока для подачи на аккумуляторную батарею 2.When using a low-voltage PEC 1 and low efficiency in the charger, a step-up voltage regulator 9 is used to provide sufficient charging voltage and current for supplying to the battery 2.

Аккумуляторы в мобильном телефоне после окончания зарядки от предлагаемого зарядного устройства имеют напряжение немногим больше допустимого минимального напряжения разрядки самих аккумуляторов зарядного устройства, следовательно, последние не имеют полной разрядки. The batteries in the mobile phone after charging from the proposed charger have a voltage A little more than the permissible minimum discharge voltage of the batteries of the charger themselves, therefore, the latter do not have a complete discharge.
