Abstract
A resonant power converter for operation in the radio frequency range, preferably in the VHF, comprises at least one PCB-embedded transformer. The transformer is configured for radio frequency operation and comprises a printed circuit board defining a horizontal plane, the printed circuit board comprising at least two horizontal conductive layers separated by an isolating layer, a first embedded solenoid forming a primary winding of the transformer and a second embedded solenoid being arranged parallel to the first solenoid and forming a secondary winding of the transformer, wherein the first and second embedded solenoids are formed in the conductive layers of the printed circuit board, wherein each full turn of an embedded solenoid has a horizontal top portion formed in an upper conductive layer, a horizontal bottom portion formed in a lower conductive layer, and two vertical side portions formed by vias extending between the upper and the lower conducting layers.
