1. A DC-DC converter comprising:
a converter unit comprising a power electronic module and an inductor, wherein:
the power electronic module comprises a switching sub-module and a diode sub-module, and
the inductor comprises a metal sheet and an insulator sheet stacked and wound into an inductor coil assembly, comprising a coil axis;
an additional converter unit comprising an additional power electronic module and an additional inductor; and
an electronic module cooling unit, comprising a heat exchanger, a fan, a manifold, and a cooling plate thermally coupled to the heat exchanger and to at least a portion of the power electronic module, wherein:
the manifold encloses the heat exchanger and is configured to direct air from the fan to the power electronic module, and
the cooling plate extends between and is thermally coupled to each of the power electronic module and the additional power electronic module.
