摘要:
A transistor switching circuit arrangement for switching at least one switching transistor on and off wherein, in order to achieve low power dissipation by delaying the change which occurs in base current to the cut-off value on conversion into the blocked state and by a subsequent brief disruptive operation of the base emitter section and in order to achieve fast switching on, there is provided a choke coil through part of which the base-emitter current of said switching transistor is fed and through part of which the current being switched is passed in positive feedback mode.
