Title POWER MEASURING APPARATUS commons meetings
Abstract

The present invention provides power measuring apparatuses of various thin film sensor types, which can easily measure, with a small configuration, power in high frequency circuits and batteries. This power measuring apparatus is provided with: a magnetic film, which is disposed in parallel to a primary conductor having a load current flowing therein

a power feed unit, which is provided with an input/output terminal that supplies an element current to the magnetic film

a bias magnetic field applying unit, which applies a direct current magnetic field that is parallel or perpendicular or diagonal to the magnetization direction of the magnetic film

and a detecting unit, which detects a voltage between the edge portions of the magnetic film in the element current direction. The power measuring apparatus detects merely a direct current voltage composition between the edge portions of the magnetic film in the element current direction.
