Contactless charging systems

Two technologies have greatly accelerated the practical use of contactless charging systems: the contactless power transformer achieved a compact size and good tolerance to misalignment by improving the core architecture, while the charging controller raised effectiveness and lowered noise with a new DC/DC converter. Specifically, the new DC/DC converter can operate buck-boost and soft-switching. A bench test and PHEV test confirmed that a contactless charging system composed of these new technologies charged stably despite gap changes and misalignment.
