Electric current sensor utilizing a compensating trace configuration

摘要

An electric current sensor employing a Hall effect generator and a ferrite substrate to be used in the measuring of electrical currents flowing in a current carrying conductor comprising a toroid core having a first and a second gap, a Hall effect generator, a current source, an amplifier, and a trace configuration positioned on the substrate for electrically coupling the amplifier to the Hall effect generator. The toroid core and ferrite substrate forming the complete magnetic circuit for the flow of the magnetic field. The trace configuration thereby being routed so as to be exposed to the magnetic field in two different impinging directions so to compensate for any unwanted induced voltages from being introduced into the output voltage thereby achieving an improved transient response.
