Comparative performance evaluations of high-voltage transformer parasitic parameter resonant inverter-linked high-power DC-DC converter with phase-shifted PWM scheme

The main purpose of this study is to analyse the inherent characteristic features and salient benefits of series, parallel, series and parallel tank inverter-fed DC-DC power converters for medical-use X-ray high-voltage generators from a practical viewpoint. The method to make the most of the harmful parasitic circuit parameters of specially-designed high-voltage transformers used in three typical resonant tank topologies is discussed on the basis of simulated results over wide load ranges
