STABILISED VOLTAGE CONVERTER WITH PROTECTION Russian patent published in 2012 - IPC G05F1/573 

FIELD: electricity.

SUBSTANCE: primary winding of a current transformer (14) is introduced into a circuit of the secondary winding of a power transformer (3). The secondary winding of the transformer (14) with one output is connected to a converter's output, and with the other one - via a diode (16) to an output of a mismatch signal amplifier (11). The voltage control circuit is closed via the mismatch signal amplifier (11), and the circuit of load current stabilisation - via the secondary winding of the current transformer (14) and the light-diode part of an optron of galvanic isolation (13).

EFFECT: higher reliability of a stabilised converter in case of overloads and short circuits of an output with simplification of its design.
