The Kaschke high power resonant transformer series is designed specifically to satisfy the requirement for small size and high efficiency power supplies. Resonant circuits are now widely used to replace standard flyback technologies as well as to power higher rated loads.
A major advantage of LLC circuits is their low noise, low loss performance. Because switching occurs at zero voltage, the switching losses are minimised and EMC issues become very easy to control.
The KRT series allows the power supply designer to control the level of stray inductance, hence removing the need for a separate resonant inductor. Our innovative design is not only a great technical advance but also allows significant cost reduction compared to standard LLC resonant circuits.
