The main purpose of this paper is to describe comparatively characteristic features and specific benefits of series, parallel and series-parallel resonant tank type inverter-fed DC-DC power converters with a high-voltage high-frequency transformer link, which are designed for 30kW to 100kW-class medical use X-ray high-voltage generators. The effective method to make the most of the harmful parasitic circuit components of the specially-designed high-voltage transformer used as the three types of resonant circuit topologies is discussed and evaluated on the basis of some simulation performance results for actual wide load variations required for the DC-DC converters in the X-ray generators. Finally, the dynamic output high-voltage responses of these resonant converters are indicated in experiments in order to confirm the unique effectiveness of the resonant tank types power converters treated here.
