An efficient, high density, inline converter module includes a power conversion circuit and an input wiring harness for connecting the input of the power circuit to a unipolar source. A second wiring harness or electrical connectors may be provided for connecting the output of the power conversion circuit to a load. Connections between a wiring harness and the power conversion circuit may comprise conductive contacts, configured to distribute heat. The power circuit may be over molded to provide electrical insulation and efficient heat transfer to external ambient air. A DC transformer based inline converter module may be used in AC adapter, vehicular, and power system architectures. An input connector for connecting the input wiring harness to the input source may be provided. In some embodiments the input source may be an AC source and the input connector may comprise a rectifier for delivering a rectified, unipolar, voltage to the input of the power conversion assembly via an input wiring harness.
