A planar transformer assembly, for use in charging capacitors of an ICD, includes windings arranged to minimize voltage across intervening dielectric layers. Each secondary winding of a preferred plurality of secondary windings is arranged relative to a primary winding, in a hierarchical fashion, such that the DC voltage, with respect to ground, of a first secondary winding, of the plurality of secondary windings, is lower than that of a second secondary winding, with respect to ground, wherein the first secondary winding is in closest proximity to the primary winding. The primary winding and each secondary winding are preferably formed on a corresponding plurality of dielectric layers. |

1. A planar transformer assembly for use in charging a plurality of capacitors stacked in series in a shocking circuit of an implantable cardioverter defibrillator, the assembly comprising:
a multilayer printed circuit board (PCB); a primary winding formed on a first layer and a second layer of the PCB; and a plurality of secondary windings, each secondary winding of the plurality of secondary windings being formed on a corresponding pair of layers of the PCB, and each secondary winding being coupled to a corresponding capacitor of the plurality of capacitors; wherein each layer of each pair of layers is separate from one another and from the first and second layers on which the primary winding is formed; and the plurality of secondary windings are arranged in a nested fashion, such that a first pair of layers, on which a first secondary winding of the plurality is formed, is located in between individual layers of a second pair of layers on which a second secondary winding of the plurality is formed. |
