Abstract :
New technologies for non-superjunction high-voltage power MOSFETs have been developed and experimentally confirmed. RON·A achieved are as low as 110% of the silicon limit and RON·QGD achieved are only 50 to 60% of the best data found. Due to the drastic improvement of RON·QGD, the developed devices have improved the power conversion efficiency of a fly-back converter by several percent. The total cost over performance of the power conversion systems can be improved by utilizing the developed technologies
