Description
Известны преобразователи однофазного напр жени в трехфазное напр жение понилсенной частоты с отношеннем частот напр жений, кратных трем.Single-phase voltage to three-phase voltage transducers are known with a frequency ratio of three times the voltage.
Предлагаемый преобразователь отличаетс от известных тем, что он составлен из трех подключенных к источнику однофазного напр жени групп вентилей, кажда из которых собрана из двух последовательно соединенных нар антипараллельно включенных вентилей и между средними точками этих вентилей подключена трехфазна нагрузка.The proposed converter differs from the known ones in that it is composed of three valve groups connected to a single-phase voltage source, each of which is composed of two series-connected antiparallel-connected valves and a three-phase load between the middle points of these valves.
Такое выполнение преобразовател позвол ет упростить его конструкцию .Such an embodiment of the converter allows to simplify its design.
На чертеже изображена принципиальна схема, преобразовател .The drawing shows a schematic diagram of the converter.
Преобразователь состоит из трех грунн вентилей, подключенных к источнику однофазного напр жени через трансформатор ТР-1. В каждую из этих групп входит по две последовательно соединенные пары антипараллельно включенных вентилей (с / по 12). Трехфазный потребитель подключен через трансформатор ТР-2 и сглаживающие дроссели к средним точкам групп вентилейПреобразование сетевой частоты в нониженпую происходит путем надлежащего чередовани зажигани вентилей различных групп.The converter consists of three ground valves connected to a single-phase voltage source through a transformer TR-1. Each of these groups includes two series-connected pairs of anti-parallel-connected valves (from / to 12). The three-phase consumer is connected through a transformer TR-2 and smoothing chokes to the middle points of the groups of valves. Conversion of the network frequency to a lower frequency occurs by proper alternation of the ignition of the valves of different groups.
