Description
Изобретение относитс к электротехнике и предназначено дл управлени вентильными преобразовател ми посто нного напр жени в переменное, состо щими из автономного инвертора и непосредственного преобразовател частоты.The invention relates to electrical engineering and is intended to control DC / DC variable-voltage converter converters consisting of an autonomous inverter and a direct frequency converter.
Известно устройство дл управлени вентильными преобразовател ми со звеном повышенной частоты, основание на вертикальном принципе управлени . Это устройство применимо дл вентильных преобразователей, состо щих из автономного инвертора напр жени и выходного расщепител уровней 1.A device for controlling converter converters with a higher frequency link is known, the base being on a vertical control principle. This device is applicable to valve converters consisting of an autonomous voltage inverter and an output level splitter 1.
Однако указанный преобразователь формирует Пр моугольно-ступенчатое напр жение на выходе и неработоспособен при активно-индуктивной нагрузке с низким коэффициентом мощности.However, this converter forms the Mougolno-step voltage at the output and is inoperable under active-inductive load with a low power factor.
Наиболее близким по технической сущности к предлагаемому вл етс устройство дл управлени преобразователем , которое содержит датчик тока.нагрузки и генератор задающего сигнала, св занные с сумматором, выход которого подключен к компаратору и интегратору, имеющему нако .пительный элемент, выход компаратора св зан с первым элементом И непосредственно, а со вторым через логический инвертор, вторые -входы элементов И св заны с пр мым и инверсным выходами блока раздельного управлени соответственно, а выхода элементов И подключены к управл ющей цепи ключа через элемент ИЛИ. Устройство работает по принципу слеже10 ни по току и обеспечивает хороший гармонический состав выходного тока преобразовател при любой форме выходного тока автономного инвертораThe closest in technical essence to the present invention is a device for controlling a converter, which contains a current sensor. Loads and a master signal generator associated with an adder, the output of which is connected to a comparator and an integrator having a positive element, the output of the comparator the element And directly, and with the second through the logical inverter, the second inputs of the elements And are connected with the direct and inverse outputs of the separate control unit, respectively, and the output of the elements And are connected to control key chain through the OR element. The device works on the principle of the following 10 current and provides a good harmonic composition of the converter output current for any form of output current of an autonomous inverter

Недостаток преобразовател в том, что при традиционном управлении вентил ми автономного инвертора тока последовательностью регул рно следующих импульсов входной ток инвер20 тора тока имеет низкочастотную модул цию , котора вызвана работой непосредственного преобразовател частоты . Подобна нестабильность входного тока недопустима дл р да ис25 точников посто нного напр жени .The disadvantage of the converter is that with the traditional control of the valves of the autonomous current inverter by a sequence of regular pulses, the input current of the current inverter has low-frequency modulation, which is caused by the operation of the direct frequency converter. Similar to the instability of the input current is unacceptable for a number of sources of constant voltage.
Цель изобретени - расширение функциональных возможностей устройства .The purpose of the invention is to expand the functionality of the device.
