The recent research status of this field is discussed. The methods of shortening rise-time, reducing droop, expanding output pulse-width, elevating insulation performance and energy efficiency and the application of closed core in high power pulse transformer design are summarized. It is focused on the realization of short rise-time, wide pulse-width and high energy transferring efficiency. For this purpose, it is feasible to select magnetic core with high permeability and high saturation magnetic flux density, using closed core and taking some special measures in fabrication. %R %U http://www.iaeej.com/xxydzgc/home %1 JIS Version 3.0.0
