Abstract: Изобретения относятся к области сварки и могут быть использованы при проектировании сварочных источников питания постоянного и переменного высокочастотного тока для ручной и полуавтоматической сварки. Согласно способу измеряют текущее значение тока питающей цепи, сравнивают его с эталонным значением, форсированно запирают проводящие в данном такте работы инвертора ключи при достижении током эталонного значения. Также формируют регулируемый временной интервал, длительность которого отсчитывают от момента отпирания ключей и которая не превышает времени насыщения сердечника выходного трансформатора. Форсированно запирают проводящие в данном такте ключи по окончании регулируемого временного интервала. Одновременно запрещают открывание всех ключей на время от момента подачи сигнала на запирание ключей и до момента установления постоянного напряжения на обмотках выходного трансформатора в данном такте работы инвертора. Сварочный источник питания состоит из выпрямителя промышленной сети с емкостным фильтром, двухтактного стабилизированного инвертора на транзисторах с выходным трансформатором и блока управления. В блок управления входят компаратор, пороговое устройство с датчиком, таймер, блок запрета включения. Согласно первому варианту блок управления содержит пороговое устройство с датчиком, таймер, блок запрета включения. В блок запрета включения входят управляющий транзистор, коллектор которого соединен с одним выводом введенного источника питания собственных нужд, другой вывод источника питания собственных нужд через введенный резистор подключен к выходу блока запрета включения, база управляющего транзистора через две цепи из последовательно соединенных диода и конденсатора подключена к первым двум входам блока запрета включения, а точка соединения указанных диода и конденсатора через введенные диоды, а также эмиттер управляющего транзистора подключены и третьему входу блока запрета включения. Согласно второму варианту блок запрета включения содержит управляющий транзистор, база которого подключена к первым двум входам блока запрета включения, эмиттер управляющего транзистора через введенный конденсатор и база управляющего транзистора через введенный резистор соединены с третьим входом блока запрета включения, коллектор управляющего транзистора через введенный резистор подключен к выходу блока запрета включения, база управляющего транзистора через введенный диод соединена с эмиттером управляющего транзистора. Изобретения позволяют управлять длительностью такта работы инвертора путем слежения за магнитным потоком сердечника или путем регулирования длительности открытого состояния силовых ключей в текущем такте, что расширяет функциональные возможности источника, позволяет уменьшить токи через транзисторы и трансформатор на холостом ходу, независимо перестраивать "жесткий" и "падающий" участки внешней вольт-амперной характеристики, повысить выходную мощность при установленных токах через силовые транзисторы. 3 с. и 2 з.п. ф-лы, 4 ил.

Abstract: FIELD: electrolytic and plasma treatment of surfaces. SUBSTANCE: proposed method includes measurement of alternating- current component and analysis of its change in time. Alternating-current component is fed to band-pass filter at limiting frequency of 500-700 and 1300-1500 Hz and voltage "u" at filter output is measured. Magnitude u 0  of threshold voltage is determined by averaging magnitude "u" for 20-40 s from beginning of treatment and time lengths t k  and "t" are read off if voltage "u" reaches magnitude (0,5-0,6)•u 0 ., 50-70 s after beginning of treatment. Termination of reading of time t k  is set by magnitude of voltage "u" equal to (0,7-1,0)•u 0 .. Moment of termination is set as magnitude "t" reaches value (1,4-1,6)•t k . Area S cleaned from coat is calculated by formula S = k•t k , where k is empirical coefficient of proportionality. In case voltage "u" does not reach magnitude (0,5-0,6)•u 0 , 50-70 s after beginning of process, process is discontinued. EFFECT: improved quality of surface. 1 dwg, 1 tbl, 1 ex
