Filed: 2001-01-09
Granted: 2002-08-20
Abstract: Изобретение относится к области электротехники и может быть использовано в устройствах электропитания для стабилизации выходного переменного напряжения. Техническим результатом предлагаемого изобретения является повышение надежности работы стабилизатора, упрощение его устройства, снижение массогабаритных показателей. Технический результат достигается тем, что стабилизатор переменного напряжения содержит трансформатор с основной, дополнительными и измерительной обмотками. Начало основной обмотки является входным и выходным зажимами стабилизатора. Стабилизатор также содержит источник питания и эталонного напряжения, двухполупериодный выпрямитель с RC-фильтром на выходе, компараторы напряжения, инвертирующие входы которых через резисторы соединены с источником эталонного напряжения, а неинвертирующие входы также через резисторы подключены к выходу RC-фильтра. По меньшей мере один из компараторов имеет положительную обратную связь. Стабилизатор также содержит транзисторные усилители, электромагнитные реле с переключающими контактами. Новизна заключается в том, что стабилизатор при числе дополнительных обмоток, равном N, содержит N+1 реле и столько же компараторов. Основная и дополнительные обмотки соединены последовательно: к концу основной обмотки подключено начало первой дополнительной обмотки, к концу каждой k-й дополнительной обмотки, где k=l, 2,..., N-1, подключено начало (k+1)-й дополнительной обмотки и нормально замкнутый контакт k-гo реле, к концу N-й дополнительной обмотки подключен нормально замкнутый контакт N-гo реле, к концу основной обмотки подключен нормально разомкнутый контакт первого реле и нормально замкнутый контакт (N+1)-го реле, нормально разомкнутый контакт которого подключен к концу N-й дополнительной обмотки. Переключающий контакт этого же реле является вторым входным зажимом стабилизатора, переключающий контакт каждого k-го реле соединен с нормально разомкнутым контактом (k+l)-гo реле, переключающий контакт N-гo реле является вторым выходным зажимом стабилизатора. Выходы компараторов соединены с входами транзисторных усилителей. 2 ил.
