A power module (1v, 1w, 1x, 1y, 1z) is disclosed. The power module (1v, 1w, 1x, 1y, 1z) includes a carrier board (410), two switches (451, 451' 452, 452'), at least one metal block (421, 42, 423), a clamping component (440) and a metal conductive component (461). The carrier board (410) includes an upper surface (102) and a lower surface (103). The two switches (451, 451' 452, 452') are disposed on the upper surface (102) and connected in series to form a bridge arm electrically connected between a positive terminal (P) and a negative terminal (N). The metal block (421, 422, 423) is electrically connected to the two switches (451, 451' 452, 452'). The clamping component (440) is disposed on the upper surface (102) and electrically connected in parallel with the bridge arm through the carrier board (410). The metal conductive component (461) is connected from a common node of the two switches (451, 451' 452, 452') to an output terminal (O). The metal conductive component (461) is located at a side of the two switches (451, 451' 452, 452') facing away from the upper surface (102).
