COMBINED FULLY CONTROLLABLE TUBE AND METHOD FOR CONTROLLING THE SAME Russian patent published in 2006 - IPC H03K17/567 

FIELD: transformation equipment, possible use in power engineering, electric engineering, in engineering of electric engines, including high voltage engines.

SUBSTANCE: combined fully controllable tube contains two branch tubes of different types connected in parallel and dampening circuit, connected in parallel to these, while each tube has native driver. First tube is one or several serially connected bipolar transistors with isolated control gate, and second tube - one or more serially connected lockable thyristors, while drivers of both tubes are connected to block for generation of primary control impulses, while a given block generates two enabling impulses and two locking impulses so, that firstly first enabling impulse is fed to first branch of combined fully controlled semiconductor tube in form of one or several serially connected bipolar transistors with isolated control gate, and then second enabling impulse is fed to second branch of combined fully controllable semiconductor valve, in form of one or several serially connected locking thyristors. When a tube is locked, firstly a first locking impulse is fed to second branch of semiconductor lockable tube, in form of one or several serially connected locking thyristors, and then second locking impulse is fed to first branch in form of one or several serially connected bipolar transistors with isolated control gate.

EFFECT: increased reliability, increased overload capacity of semiconductor tube and decreased static and dynamic losses.
