TRANSFORMER TECHNIQUE FOR TRANSISTOR CONTROL Russian patent published in 2015 - IPC H03K3/33 

FIELD: physics, control.

SUBSTANCE: invention relates to transistor control and can be used in automation, telemechanics and robotics. A transformer technique for controlling a transistor is characterised by that the output controlled power circuit of the transistor is galvanically decoupled at the base with the low-ampere control circuit by transformer coupling of the secondary coil of the transformer, which may or may not have a core, wherein the control circuit has a catcher as the primary coil of the transformer, which may have a power supply independent of the controlled circuit.

EFFECT: providing reliable isolation between a control circuit and a controlled circuit.
