Description

Изобретение относитс к электротехнике и преобразовательной технике и может быть использовано дл получени на выходе устройства посто нного напр жени как повышенной, так и пониженной величины по сравнению с величиной входного напр жени посто нного тока.The invention relates to electrical engineering and converter technology, and can be used to produce, at the output of a constant voltage device, both an increased and a reduced value compared to the value of the input voltage of a direct current.

Известны преобразователи посто нного напр жени в посто нное, которые содержат конденсаторы и управл емые ключи 1 .DC-to-DC converters are known which contain capacitors and controllable switches 1.

Недостатком этих преобразователей вл етс наличие гальванической св зи между входом ц выходом устройства.The disadvantage of these converters is the presence of galvanic connection between the input and output device.

Наиболее близким по технической сущности к изобретению вл етс преобразователь посто нного напр жени в посто нное, содержащий два входных и два выходных выхода дл подключени соответственно преобразуемого напр жени и нагрузки, .конденсаторы, включенные параллельно входным и выходным выводам, управл емые ключи и четырехполюсник , имеющий входные и выходные выводы 2.The closest to the technical essence of the invention is a constant-voltage-to-constant-voltage converter containing two input and two output outputs for connecting respectively converted voltage and load, capacitors connected in parallel with input and output pins, controlled keys and a quadrupole, having input and output pins 2.

Основным недостатком этого устройства вл етс 1-альваническа св зь между входом и выходом, что не позвол ет использовать его в качествеThe main disadvantage of this device is the 1-alvanic relationship between the input and the output, which prevents its use as a

автономного вторичного источника питани . Кроме этого, преобразователь позвол ет передавать энергию лишь в сторону повышени напр жени . Все это сужает функциональные возможности устройства.autonomous secondary power source. In addition, the converter allows energy to be transmitted only in the direction of increasing voltage. All this reduces the functionality of the device.

Следует также отметить ,что в выходном напр жении преобразовател имеютс значительные пульсации, что вл ет10 с также недостатком известного устройства.It should also be noted that there are significant pulsations in the output voltage of the converter, which is also 10 with the disadvantage of the known device.

Цель изобретени - расширение функциональных возможностей и уменьшение пульсаций выходного напр же15 ни преобразовател .The purpose of the invention is to expand the functionality and reduce the ripple of the output voltage of the converter.

Указанна цель достигаетс тем, что преобразователь посто нного напр жени в посто нное, содержащий два входных и два выходных вывода This goal is achieved by the fact that the DC / DC converter contains two input and two output terminals.

Claims

20 for connecting respectively convertible voltage and load, capacitors connected in parallel to the input and output pins, controlled keys and a quadrupole having input and output pins, are made so that the quadrupole contains two longitudinal branches consisting of sequentially connected controlled keys and included, respectively, between the first and second inlet and output terminals, and transverse branches, consisting of capacitors connected to the first and second branches, and between the ends of the previous The first and subsequent capacitors connected to one branch, as well as between one end of the previous capacitor connected to the first branch and the end of the next capacitor connected to the second branch, include controllable keys, and the first input and output pins of the quadrupole are connected the terminals of the device, and the second input terminal of the quadrupole are connected via separate controllable keys to the second input and output terminals of the device. In addition,: an additional similar voltage transformer is introduced into a constant voltage connected in parallel with the main one. The drawing shows a converter circuit. The device contains two input 1 and 2 and two output 3 and 4 outputs, capacitors 5 and 6 included in the input and output of the device, controlled keys 7-10 quadrupole 11, consisting of two longitudinal arms with controlled keys 12-15 and transverse capacitors 16-18 ,. and so controlled keys 1.9 and 20, connected to opposite ends of capacitors 16-18. In parallel, a similar converter 21 is connected. The converter operates as follows. Suppose that a DC power source is connected to 1 and 2 pins, and a load to 3 and 4 pins, then with closed keys 7, 8, 12 13, 14 and 15 (the other keys are open), capacitors 16-18 are connected in parallel source and charged before the voltage source E. If you now close the keys 9, 10, 1 and 20, and open the rest, then the load connected to pins 3 and 4 will have a voltage exceeding the voltage of the source, those. n, where n is the number of capacitor quadrupole 11. When terminals 3 and 4 in any mode of operation, the converter is galvanically developed (through the resistance of private keys) from terminals 1 and 2. It is easy to see that when a constant voltage source is connected and 4, and the load to terminals 1 and 2, when alternately closing and opening the scientific research institute, the group of keys 9, 10, 19, 20 and the group of keys 7, 8, 12, 13, 14, 15 on terminals 1 and 2 will be a voltage equal to Е /P. Thus, the proposed converter provides energy transfer with both increasing and decreasing voltage, and both pairs of terminals can be used as input or output. When using common key elements, the galvanic between the outputs of the converter is practically absent. To reduce the output voltage ripple parallel to the main transducer, a similar additional transducer is used, which operates in protiphase with the main one. Claim 1.

The converter according to claim 1, is also so tangible that, in order to reduce output voltage ripple, an additional analogous DC voltage constant-to-constant voltage converter connected in parallel with the main one is introduced.
