Transformer with overshoot compensation coil

摘要

A transformer that comprises a winding assembly, a first and a second output terminal and a first and a second conductive path. The winding assembly includes a first and a second winding assembly terminal, a winding coupled between the first and second winding assembly terminals, and a resistive load coupled between the first and second winding assembly terminals. The resistive load has a resistance and an intrinsic inductance effectively in series with the resistance. The first conductive path connects the first winding assembly terminal and the first output terminal. The second conductive path connects the second winding assembly terminal and the second output terminal. The first and second conductive paths enclose an area through which magnetic flux can pass so as to provide a pickup loop inductance between the first and second output terminals. The first conductive path includes a compensation coil having a compensation inductance sufficient to reduce output overshoot at the first and second output terminals caused by the intrinsic inductance and the pickup loop inductance.
