По основному авт. св. № 269284 известен регулируемый выпр митель, выполненный на диодах с использованием одного тиристора, который включен между общей точкой электродов двух диодов в катодной или анодной группе выпр мител и одноименным электродом третьего диода той же группы. Однако такой выпр митель имеет ограниченный диапазон регулировани ,According to the main author. St. No. 269284 is known an adjustable rectifier made on diodes using one thyristor, which is connected between the common point of the electrodes of two diodes in the cathode or anode group of the rectifier and the same electrode of the third diode of the same group. However, such a rectifier has a limited range of control,
11;елью изобретени вл етс расширение диапазона регулировани выпр мител . Это достигаетс тем, что предлагаемый выпр митель снабжен дополнительным тиристором, включенным между обще:й точкой смежных диодов противоположной группы и одноименным электродом третьего диода той же11; the purpose of the invention is to expand the range of adjustment of the rectifier. This is achieved by the fact that the proposed rectifier is equipped with an additional thyristor connected between the common point of adjacent diodes of the opposite group and the same electrode of the third diode of the same type.

На фиг. 1 дана принципиальна схема описываемого выпр мител дл случа питани его от трехпроводного трехфазного источника; на фиг. 2 - то же дл случа питани от четырехпроводного трехфазного источника .FIG. 1 is a schematic diagram of the described rectifier for the case of supplying it from a three-wire three-phase source; in fig. 2 is the same for the case of power from a four-wire three-phase source.
При питании выпр мител от трехпроводного трехфазного источника 1 питани на тиристор 2 подаетс двухфазное напр жение через диоды 3-5, а на тиристор 6 - через диодщ 7-9. Измен угол регулировани управл ющих импульсов на тиристорах 2 и 6, можно измен ть напр жение на нагрузке 10 от нул до максимальной величины .When powering a rectifier from a three-wire three-phase power supply 1, thyristor 2 is supplied with two-phase voltage through diodes 3-5, and to thyristor 6 through diode 7-9. By varying the control angle of the control pulses on the thyristors 2 and 6, it is possible to vary the voltage at the load 10 from zero to the maximum value.
При питании выпр мител от четырехпроводного источника трехфазного напр жени в схему ввод тс два дополнительных диода 11 и 12.When powering the rectifier from a four-wire three-phase voltage source, two additional diodes 11 and 12 are introduced into the circuit.
