Abstract
The present invention provides a DC-DC power converter that comprises two or more Printed Wiring Boards (PWB) mounted parallel to one another and without encapsulation. Electronic components can be mounted on both sides of each board. The open design and parallel orientation of the PWBs allow airflow over components mounted on the PWBs. The PWBs are preferable made of FR-4 with copper foils, with one thicker board being comprised of more copper layers and the other boards comprised of less copper layers. In the preferred embodiment, the power processing elements are housed in the thicker PWB, while the thinner boards house the control circuitry.
