POWER SUPPLY SYSTEM, POWER CONVERSION APPARATUS, AND POWER SYSTEM

WIPO Patent Application WO/2023/092553

A1

The present application provides a power supply system, a power conversion apparatus, and a power system. The power supply system may comprise a photovoltaic array and a power conversion apparatus coupled to the photovoltaic array; the power conversion apparatus comprises a power cavity, a heat dissipation cavity, a power device, a magnetic element, and at least one first heat dissipation device and second heat dissipation device; the power cavity and the heat dissipation cavity are communicated with each other to form a first air duct; the power device is disposed in the power cavity; the at least one second heat dissipation device is disposed in the heat dissipation cavity; each first heat dissipation device can be connected to the power device; the magnetic element is disposed in the first air duct. During operation of the power conversion apparatus, the power device and the magnetic element generate heat. At this time, each first heat dissipation device can dissipate the heat generated by the power device, and each second heat dissipation device can dissipate the heat generated by the magnetic element. In the present application, the first heat dissipation device and the second heat dissipation device can be respectively provided to dissipate the heat from the power device and the magnetic element, and the heat dissipation capability is strong.
