Non-inductive lead path hall effect electrical current sensor |
摘要 |
An electric current sensor employing a Hall effect generator to be used in measuring electrical currents flowing in a current carrying conductor including a printed circuit board, an amplifier, a control current source, a toroid core having a gap, a Hall effect generator, and first and second traces configured on the printed circuit board so as to be non-inductive when exposed to the impinging magnetic field concentrated by the toroid core across the gap and across the Hall effect generator. The non-inductive configuration of the first and second traces is composed of a plated through hole electrically coupling the first and second traces to form a loop having a loop area equal to zero that is perpendicular to the directional flow of the impinging magnetic field thereby preventing the generation of unwanted induced voltages in the current sensor.
