FIELD: electricity.
SUBSTANCE: method of protection of the output stage of the amplifier from overloads in respect to current consists in the fact that they determine the current in a circuit of the driver amplifier, compared to the received value of current with the predetermined value If value of the current exceeds the preset value, a signal of protection on the current is formed, which turns off the output power transistors of the driver amplifier, thus the current in the circuit of the driver amplifier determined on the basis of capacity define on the basis of a power failure on one of the output power transistors of amplifying the capacity.
EFFECT: increase of speed of the device of protection of the output cascade of the amplifying of the capacity from an overload on the current
