<p>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.</p> |
