Murata’s innovative and patented pdqb winding technology makes it possible to construct transformers of up to and over 400kW that can operate at frequencies as high as 250kHz. The pdqb winding technique overcomes the skin and proximity effects as well as other high frequency losses associated with conventional construction methods, delivering an efficient (>99.5 %) solution in a compact footprint.
Thermal performance is also improved, increasing power density while eliminating the space requirements and cost associated with heatsinking. Each design can be optimized by a combination of Murata’s transformer expertise and their own simulation software.
These transformers are ideally suited to fast switching, high power applications such as eV fast charging, rail, and smart grid energy.
