摘要： The present invention provides various thin-film sensor type power measuring apparatuses which can be constructed in a simplified and compact structure so as to measure the power of high-frequency circuits or batteries. This power measuring apparatus includes: a magnetic film disposed in parallel to a primary conductor through which a load current flows; a power supply with input and output terminals for supplying an element current to the magnetic film; a bias magnetic field applying unit for applying a DC magnetic field in a direction that is parallel, perpendicular, or diagonal to the direction of magnetization of the magnetic film; and a detection unit for detecting the voltage between the ends of the magnetic film in the direction of the element current. The power measuring apparatus detects only the DC voltage component between the ends of the magnetic film in the direction of the element current

摘要： An improved laminated ferromagnetic figure 8 power meter core is provided. The core is (31) fabricated from a plurality of ferromagnetic plates (37) and is formed in the general shape of a figure 8. The central leg (34) of the core has a cross-sectional area that is larger than the cross-sectional area of other parts of the core. The core gap, in which a Hall-effect sensor (36) is located, has gap faces with chamfered or rounded over edges to reduce fringing and bypassing effects. The core is formed without discontinuous corners that can result in local saturation and, in use, accommodates electrical power conductors (38, 39) in an over-under looping relationship through the openings of the core to provide a more homogeneous magnetic flux within the core and thus more reliable metering. The overall result is a core with a higher saturation point and thus a wider dynamic range than prior art cores.
