Innovative high power and high-frequency transformers

Murata’s innovative and patented pdqb winding technology makes it achievable to build transformers of up to and above 400kW that can function at frequencies as high as 250kHz. These devices are available now from TTI Europe.

The winding technique overcomes the skin and proximity effects and other high-frequency losses linked with conventional construction methods, producing an efficient (>99.5%) solution in a compact footprint.

Thermal performance is also increased, improving power density while removing the space demands and cost associated with heatsinking. Each design can be optimised by combining the company's transformer expertise and its own simulation software.

These transformers are ideal for fast switching, high power applications such as eV fast charging, rail, and smart grid energy.
