сти от величины отклонени  регулируемого параметра (температуры или истребл емой мощности) от заданной. Формула изобретени  1.Регулируемый тиристорный иреобразователь неремениого наир жени  дл  двух активных нагревателей, содерл ащий два тиристора, анод одного из которых соединен с катодом другого и с одним из входных выводов, нри этом катод нервого тиристора соединен с выводом дл  подключени  первого нагревател , а второй входной вывод соединен с выводом общей точки дл  подключени  нагревателей, о т л и ч а ющ и и с   тем, что, с целью обеспечени  одинаковой мощности в нагрузках во всем диапазоне регулировани , в него введен третий тиристор, анод которого соединен с катодом первого, а катод - с анодом второго, а анод второго тиристора соединен с выводом дл  подключени  второго нагревател . 2.Способ управлени  преобразователем 110 п. 1, заключающийс  в подаче управл ющих импульсов на тиристоры и изменении их углов регулировани , о т л и ч а ю щ и йс  тем, что при потреблении менее половины максимальиой мощности импульсы иодают на первый и второй тиристоры и измен ют их угол регулировани , а при потреблении более половины максимальной мощности управл ющие импульсы подают на все тиристоры, причем на первый и второй - при углах естественного зажигани , и измен ют угол регулировани  импульсов на третьем тиристоре. Источники информации, прин тые во внимание при экспертизе 1.Гельман М. В., Лохов С. П., Тиристорные регул торы переменного напр жени . М., «Энерги , 1976. STI from the deviation of the controlled parameter (temperature or power demand) from the set one. Claim 1. Adjustable thyristor irresistive transducer for two active heaters, containing two thyristors, the anode of one of which is connected to the cathode of the other and one of the input terminals, the cathode of the thyristor nerve is connected to the output for connecting the first heater, and the second An input terminal is connected to a common point for connecting heaters, which is required so that, in order to ensure the same power in the loads throughout the control range, a third tiris has been entered into it A torus, the anode of which is connected to the cathode of the first, and the cathode to the anode of the second, and the anode of the second thyristor is connected to the output for connecting the second heater. 2. The control method of the converter 110 p. 1, which consists in supplying control pulses to the thyristors and changing their control angles, which means that when less than half of the maximum power is consumed, the pulses iodine to the first and second thyristors and change their control angle, and when more than half of the maximum power is consumed, control pulses are applied to all thyristors, and to the first and second - at natural ignition angles, and the pulse control angle is changed to the third thyristor.
