Description

Из приведенной схемы видно, что контурный ток при переключении отводов обмотки трансформатора в данном случае вообще не может возникнуть, так как далее пр« подаче импульсов на включаемые к выклкучаемые тиристоры многофазного упраал емого моста 2 замкнутой цепи дл  контурного тока не создаетс  нз-за невозможности однов|1ем8нного включени  основного 3 и дополнительного 4 транзнсторов .From the diagram, it can be seen that in this case, the loop current when switching the transformer windings cannot occur at all, since then the supply of pulses to the switched-on thyristors of the multiphase controlled bridge 2 of the closed circuit for the loop current does not create | 1m8n the inclusion of the main 3 and additional 4 transistors.

Таким образом, в данном устройстве контурный ток не ограничиваетс , как в нзвестном устройстве, а исключаетс  полностью .Thus, in this device, the loop current is not limited, as in the known device, but is completely eliminated.

Кроме того, в случае фазоступенчатого регулировани  установленна  мощность транзисторов предложенного устройства может быть значительно ниже| чем в известном устройстве, так как основной транзистор в последнем работает в очень т желом режиме ключевого токоограничени .In addition, in the case of phase-phase regulation, the installed power of the transistors of the proposed device can be significantly lower | than in the known device, since the main transistor in the latter operates in a very severe mode of a key current limiting.
