US Patent 10264709 Power output end structure of power supply

A power output end structure of a DC power supply is disclosed. The power supply includes a casing provided with a plurality of power modules. Output terminals of the power modules are electrically connected to a positive busbar and a negative busbar, respectively. The positive busbar and the negative busbar are in the form of a thin plate and arranged horizontally. The power modules are electrically connected in parallel or in series. Because the positive busbar and the negative busbar are in the form of a thin plate and arranged horizontally, the heat dissipation path in the casing won't be blocked so as to provide a better heat dissipation space and achieve a better heat dissipation effect.
