Title:
POWER ASSEMBLY WITH INTEGRATED CURRENT SENSING
Document Type and Number:
Japanese Patent JP3453115
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a power assembly using current sensing technology to solve the limitation of a sensing current and a problem such as cost.
SOLUTION: A semiconductor module has an electrically conductive heat sink base plate with a power semiconductor and printed circuit board. The printed circuit board mounted on the heat sink has a control circuit for the power semiconductor. A rigid L-typed electrode, connected to an electrode of the power semiconductor, is fitted to the base and extends upward adjacent to the edge of the printed circuit board. A Hall sensor mounted on the printed circuit board is positioned in a magnetic field created by a current in the electrode to capture the magnetic field. Magnetic substances fitted to both sides of a Hall element cause the magnetic field that pass the Hall sensor to concentrate.
