FIELD: electrical engineering.
SUBSTANCE: invention relates to instrument making in electrical engineering, namely to construction of sensors of orthogonal components of electric network current, which enable to ensure correct operation of automatic control system of active and reactive power of generators and electric receivers. Disclosed is a device for multiplying an analogue signal by a discrete signal, comprising two parallel-connected complementary transistors, the collectors of which are combined and connected to a connection point, and emitters are also combined and connected to zero bus, bases of which are connected through resistors to different poles of secondary winding of transformer.
EFFECT: increased reliability and performance by reducing switching time.
