ABSTRACT:
A high power, high frequency toroidal inductor is broken into four quadrant cores and uses bare rectangular conductors to form coils. One coil is wound centrally around each quadrant. The coils positioned centrally on the quadrants minimize the effect of damaging fringe flux and leakage flux. The coil inner winding ends are bent perpendicular to the coils to form tangential leads with one coil inner tangential lead joined to an adjacent outer coil radial lead by jumpers that span adjacent coils.
