Claims (1)

Полумостовой автогенератор, содержащий верхний и нижний силовые транзисторы, соединенные по полумостовой схеме, каждый с обратным диодом, и схему запуска, отличающийся тем, что в него введены схемы управления силовыми транзисторами, идентичные для верхнего и нижнего транзисторов, которые преобразуют синусоидальное напряжение вторичных обмоток трансформатора в ток прямоугольной формы, подаваемый в базы силовых транзисторов, и активно запирают выходные транзисторы при их выключении, схема защиты по току с внешней регулировкой ее уровня, которая подключена по крайней мере к нижнему силовому транзистору полумоста, и схема блокировки тиристорного принципа, которая запускается сигналом со схемы защиты по току и имеет сброс в исходное состояние на каждом нерабочем для данного силового транзистора полупериоде автоколебаний.A half-bridge oscillator containing the upper and lower power transistors connected in a half-bridge circuit, each with a reverse diode, and a starting circuit, characterized in that it includes control circuits for power transistors that are identical for the upper and lower transistors, which convert the sinusoidal voltage of the secondary windings of the transformer into a rectangular current supplied to the base of power transistors, and the output transistors are actively locked when they are turned off, the current protection circuit with external adjustment of its level , which is connected at least to the lower half-bridge power transistor, and the thyristor principle blocking circuit, which is triggered by a signal from the current protection circuit and has a reset state for each half-cycle self-oscillation that is not working for a given power transistor.
