The MT series creatively addresses the key characteristics of high quality matching transformers for high frequency / high power applications.
The skin effect in the MT is negligible due to its unique laminar structure. Instead of the traditional copper tubes, the MT winding is made of laminar copper sheets. At 350 kHz this revolutionary structure reduces resistive losses by a factor of 10, and consequently increases overall efficiency to above 90%.
The coupling coefficient of the MT is exceptionally high. Using alternating primary and secondary layers of thin copper sheets creates unprecedented coupling and very low reactive losses. The MT was designed to achieve zero stray inductance. This advanced design results in short circuit voltage of less than 10%, so that over 90% of the available reactive power is transmitted to the load.
The MT completely avoids de-rating of specification when tapped, through an innovative yet simple combination of identical coil elements that are connected in series and parallel. This enables the transformation ratio to be modified quickly and without power reduction.
The frequency range of the MT is exceptionally wide: 5 – 350 kHz. This is made possible by practically eliminating stray inductance, as well as by using high saturation ferrite.Specifications
