Respective alternately-conductive parallel amplifier paths are controlled by the control terminals. A low pass filter and current mirror is responsive to the combined currents flowing in the parallel amplifier paths for producing a low pass filtered signal. A detector output stage is responsive to the low pass filtered signal. Each of the pair of amplifier elements includes a respective impedance through which flows current from the respective amplifier path and current from the respective control terminal.

摘要： A method of preventing an overload current from a power supply to a load through a ground fault circuit interrupter includes the steps of: obtaining an interrupted fault current from a hot wire to a ground wire via a first zero-phase current inductor and a fault current from a neutral wire to the ground wire via a second zero-phase current inductor; amplifying a signal of the fault current by an Op-Amp; and determining the fault current by a programmable control module, wherein when the fault current is larger than a preset threshold, the programmable control module sends a control signal to a control switch such that the control switch electrifies a second coil of a trip breaker to drive an armature at an unlocked position, so as to separate a movable terminal with a fixed terminal for electrically disconnecting the load with the power supply.
