POWER MODULE, POWER SUPPLY SYSTEM, VEHICLE, AND PHOTOVOLTAIC SYSTEM

The present application provides a power module, a power supply system, a vehicle, and a photovoltaic system. The power module comprises a first metal-clad substrate, a plurality of chips, and a first connecting piece; a first electrode of each chip is electrically connected to a first metal layer of the first metal-clad substrate; the first connecting piece comprises a first main body portion and a plurality of first contact portions; a second electrode of each chip in the plurality of chips is in contact with at least one first contact portion; a part of the first main body portion is formed between at least one pair of adjacent first contact portions. In the present application, a current flowing out from each chip can directly flow into the first main body portion by means of the corresponding first contact portion, thereby shortening the current flow path; the chips are connected in parallel by means of the first connecting piece, thereby reducing the parasitic inductance of the power module, and improvi
