REDUNDANT DIRECT CURRENT STABILISER Russian patent published in 2014 - IPC G05F1/56 

FIELD: electricity.

SUBSTANCE: invention refers to electric engineering and can be applied in spacecrafts for current limitation in electric power supply system of solar battery panel opening for a drive opened to the limits. Redundant DC stabiliser includes control element (CE) connected in series with current sensor and load and based on four n-channel MIS transistors connected in parallel and in series, negative CE output connected via current sensor to common power supply bus and positive output connected via load to positive power supply bus; four identical control circuits (CC) of CE MIS transistors are added; each CC output is connected to gate of separate MIS transistor of CE; negative power supply output of each CC is connected to common power supply bus and positive output is connected to positive power supply bus; gauge input of each CC is connected to the point of CE connection with current sensor; each CC includes input non-inverting amplifier with its input connected to CC gauge input and output connected to inverting input of output amplifier (OA), output of which is connected to CC output; reference voltage source with its output connected to non-inverting input of OA; power supply pulse generator with its output connected to inverting OA input.

EFFECT: improved reliability of DC stabiliser.
