Abstract: A magnetic-component module includes a substrate, a core on a first surface of the substrate, a spacer on the core, a gap between a bottom surface of the core and the first surface of the substrate, a winding including wire bonds extending over the core and electrically connecting a first portion of the substrate and a second portion of the substrate, and traces on and/or in the substrate, and an overmold material encapsulating the core, the spacer, and the wire bonds and filling the gap.

Abstract: A power supply apparatus includes a converter, an output voltage detector, an output voltage controller that performs control to make a detected value of an output voltage of the power supply apparatus approach a target value in accordance with a comparison result between an output voltage of the converter and a reference voltage, and an instructed value reader that reads an instructed value regarding the output voltage from outside. A pre-bias voltage is applied across output terminals from an external circuit connected to the output terminals also during a time when the converter stops an operation. At a time when the converter starts to operate, the output voltage is set such that the output voltage becomes identical or approximately identical to a pre-bias voltage. After the output voltage has become identical or approximately identical to the pre-bias voltage, the output voltage is set such that the output voltage becomes an instructed voltage instructed from outside.
