Abstract:
An inductor built into a printed circuit board (hereinafter PC board), comprising:a first electrically conducting trace of said PC board serving as a positive output bus of a power supply built on said PC board; a second electrically conducting trace serving as a negative output bus of said power supply; a ferromagnetic core placed around said first trace and said second trace to form a first inductor by said first trace passing through a first opening in said ferromagnetic core, and to form a second inductor by passage of said second trace through a second opening in said ferromagnetic core; and at least one sense line to measure a voltage level in a load to which electrical power is delivered by said positive output bus and said negative output bus, and said at least one sense line passes through a said opening in said ferromagnetic core.
