CIRCUIT BOARD AND POWER CONVERSION DEVICE WITH SAME

The present invention is applicable to the field of circuit board technologies, and discloses a circuit board and a power conversion apparatus having the circuit board. The foregoing circuit board includes a substrate and a magnetic core, where the magnetic core is embedded into the substrate, at least one turn of a winding conductor wound around the magnetic core is arranged on the substrate, each turn of the winding conductor includes a first end-surface conductor and a second end-surface conductor that are separately arranged on two ends of the magnetic core, and each turn of the winding conductor further includes a first side-surface conductor that penetrates through the magnetic core from an inner side of the magnetic core and a second side-surface conductor that penetrates through the magnetic core from an outer side of the magnetic core. The power conversion apparatus includes the foregoing circuit board. According to the circuit board and the power conversion apparatus having the circuit board provided by the present invention, the magnetic core is embedded and different manners of winding the magnetic core are used to reduce the usage area of the substrate and flexibly use a wire routing space of a conductive layer of the substrate, which achieves larger inductance, saves materials, and reduces cost for fabricating a power conversion apparatus.
