Feasible characteristic evaluations of resonant PWM inverter-linked DC-DC power converter using high-voltage transformer parasitic circuit components

The main purpose of this paper is to describe some of the particular characteristic features and inherent benefits of series, parallel and series-parallel resonant tank inverter-fed DC-DC power converters for medical-use X-ray high-voltage generators from a practical viewpoint. The method to treat the harmful parasitic circuit parameters of the high-voltage transformer used in the three typical resonant tank topologies is discussed on the basis of some simulated results as compared with extremely wide load ranges found in the X-ray generator.
