FIELD: radio-electronics, possible use for increasing reliability of operation of onboard radio-electronic equipment by protecting it from high power impulse commutation overloads, occurring in constant current power supply networks due to transition processes in case of regular and emergency consumer commutations.
SUBSTANCE: protection device contains high voltage electronic key on IGBT-module, operating during effect of impulse commutation overload in the mode of reducing relay voltage stabilizer, where the energy of powerful interferences is partially transferred to output filter of device and used as power for consumer. Device disconnects the consumer in case of extended excess of set value by powering network voltage, and also protects the network from current overloads in the moment of consumer enabling and in case of emergency shorting.
EFFECT: ensured continuous provision of power to protected consumer in case of impulse commutation overloads.
