Abstract

A matrix transformer and/or inductor module has its terminations bonded rigidly to the ferrite core of which it is made. Because the ferrite core is strong and dimensionally stable, the terminations are rugged and precisely located, important criteria for assembly to printed circuit boards and the like, especially if automated assembly methods are used. In another embodiment, the module has top and bottom metal plates which are the high current output terminals. This module can be mounted sandwiched between live heat sinks. In another embodiment, deep grooves are made into the core material, and fins are bonded into the grooves. The grooves reduce core losses by reducing eddy currents and dimensional resonance effects, and the fins remove heat from within the core allowing operation at much higher flux density and frequency.
