Description

Известны преобразователи посто нного тока в пере.меппьи па полупроводниковых триодах с магнитной св зью между цеп ми коллектора и базы, которые предназначены дл  э,тек1ропитани  спнхронпых двчгателей напр жением со стабилизированной частотой, с целью получени  высокостабильного числа оборотов привода.There are known direct current converters in ac circuits for semiconductor triodes with magnetic coupling between the collector and base circuits, which are designed to emit power from the synchronous dvigateli with voltage with a stabilized frequency, in order to obtain a highly stable number of revolutions of the drive.

Недостатки подоб1 ых преобразователей состо т в том, что дл  получени  пр моугольной формы импульса напр жени  и малых потерь н управл юпдих цеп х триодов преобразовател  приходитс  примен ть трансформаторы, изготовленные из специальных сталей, а дл  упраиле ни  частотой выходного напр жени  - магпитопроводы с/южной формы с регулируемым зазором.The disadvantages of such converters are that in order to obtain a rectangular voltage pulse and a small loss of control of the triode circuits of the converter, it is necessary to use transformers made of special steels, and for control of the output voltage frequency - magnetic current with / southern shape with adjustable clearance.

Дл  устранени  этих педостатков в описывае.мом преобразователе коммутаци  полупроводниковых триодов осуществл етс  при помощи управл ющего дроссел  с сердечпико.м i:s материала с пр моугольной петлей гистерезиса.To eliminate these pedo-devices in the described converter, the switching of semiconductor triodes is carried out using a control droplet with a hearth i: s material with a hysteresis square loop.

Дл  обеспечени  возможности уг|равлени  частотой выходного папр жепи  переменного тока сердечник дроссел  делаетс  Ш-обра:Л1ой формы и сиабжаетс  обмоткой подмагничпв;:пи . Схема преобразовател  приведена на чертеже. Полупроводниковые триоды и 2 коммутируютс  поочередно. Когда ток проходит триод /, на дроссель 3 подаетс  суммарное напр жение обмоток 4 и 5 выходного трансформатора. При этом напр жепие на конце обмотки 6 дроссел  3, присоединенном к базе триода 1, близко к нулю (относительно земли), а иапр жеиие иа конце обмотки 7, присоединенно М к базе триода 2, равно удвоенному напр жению источника питани . Это напр жение поддерживаетс  иосто иным вследствие линейного нарастани  магнитного потока в выходном трансформаторе. Ток, проход щий через обмотки и 7 дроссел  3, возрастает, а магнитный поток его увеличиваетс  до тех пор, пека не насыщени . При насыщении сердечника дроссел  3 резко уменьшаетс  индуктивное сопротивление обмоток 6 ц 7, что вызывает запирание триода / и отпирание триода 2. Затем процесс продолжаетс  апалогичпо предыдущему и происходит запирание триода 2 и отпирание триода /, т. е. схема возTo ensure the possibility of directing the output frequency of the alternating current, the core of the throttles is made X-obra: of the 1st form and connected to the winding of the paramagnetic cable; Diagram of the transducer shown in the drawing. The semiconductor triodes and 2 are switched alternately. When the current passes through the triode /, the total voltage of the windings 4 and 5 of the output transformer is applied to the choke 3. At the same time, the tension at the end of the winding 6 of the throttles 3 connected to the base of triode 1 is close to zero (relative to the ground), and the distribution at the end of winding 7 connected to the base of triode 2 is equal to twice the voltage of the power source. This voltage is maintained and otherwise due to a linear increase in the magnetic flux in the output transformer. The current passing through the windings and 7 droplets 3 increases, and its magnetic flux increases until the pitch is not saturated. When the core of the throttle 3 is saturated, the inductive resistance of the windings 6 c 7 decreases sharply, which causes the locking of the triode / and unlocking of the triode 2. Then the process continues apologic to the previous one and locking of the triode 2 and unlocking the triode /, i.e.
