FIELD: electrical engineering.
SUBSTANCE: voltage commutator with the current overload protection comprises a current pickup, an electronic gate composed of a two-step follower feeding the load unit. The additional aperiodic component, a transistor and a diode connected in series to the source-emitter junction of the said transistor are connected in the gate control circuit as an electronic shunt to interrupt current flowing through the load.
EFFECT: expanded performances thanks to current overload protection.
