摘要： A DC/DC converter for use in power supply applications employing multiple parallel-connected converters employs a digital controller referenced to the secondary or output side of an isolation boundary and having non-isolated direct connections to secondary side components. The controller directly monitors output voltage and output current and uses feedback control techniques to precisely control these values in a desired manner. The DC/DC converter can implement so-called “droop” current sharing with increased accuracy arising from the secondary-side digital control, so that a desired balanced sharing of current across multiple converters can be achieved. The converter uses calibration establish accurate set points, and any of a variety of additional functions/features to attain operational goals.

摘要： A magnetic field generating device is disclosed having an arrangement of permanent magnets, each permanent magnet (PM) having a north end and a south end, and each aligned in the same north-south orientation. The PM arrangement is configured to have a surface at the north polarity end, a surface at the south polarity end, or a surface at both ends. A layer of ferromagnetic material is securely disposed at one of the surfaces of the PM arrangement, the layer having a thickness equal to or less than about 15 millimeters.
