A 98.4% Efficiency 380V-12V DCX With 1.3kW/in3 Power Density Using Low NFoM Devices and Resonant Drive Transformer

The MHz series resonant converter (SRC) dc transformer (dcX) is attractive for its good soft-switching characteristics, which is suitable for high efficiency high power density applications. For a 380-12 V dcX, it has been proved that using series-connected low voltage devices with low NFoM can redu...
