Abstract: A high frequency matrix transformer comprises a plurality of interdependent magnetic elements (101) arranged and interwired to provide very low leakage inductance and very good coupling from the primary (102) to the secondary (103). The matrix transformer is particularly well adapted for high equivalent turns ratios, high frequency, high power, and high dielectric isolation. It can have parallel secondaries (103) which can source current to parallel rectifier circuits (CR1, CR2) with current sharing. It can also have parallel primary circuits (102) to balance the load between source switching circuits (Q1, Q2) to provide dual input voltage capability. The matrix transformer can be very flat, making it easy to ventilate or heat sink. The matrix transformer having push pull windings can include the primary switching means (Q1, Q2) and secondary rectifying means (CR1, CR2) within its windings, so that the transformer as a whole has direct current inputs and outputs.

Abstract: A multipin (116) matrix capacitor includes a first (100) and second (200) electrode separated by a dielectric material to form a capacitive element and includes terminals (130, 132) for connecting it to the first and second electrode wherein the terminals are distributed along the electrodes in a grid arrangement. Inductances are minimized or substantially eliminated in lead connections to the matrix capacitor due to the reduced conduction path lengths possible between an external component and the capacitor since access to the capacitor is provided at substantially all areas of the electrodes forming the capacitor. In one aspect of the invention, DC current is conducted along the surface of conductive sheets comprising the electrodes.
