Practical circuit modeling and circuit design of high-frequency high-voltage transformer for medical-use inverter type X-ay High-voltage high-power generator

摘要

The main purpose of this paper is to describe an equivalent circuit modeling and its circuit parameter estimation of the high-frequency high-voltage transformer for series and parallel resonant tank high-frequency AC linked DC-DC converter which is applied to the medical-use X-ray high-voltage power generator from a practical point of view. A design procedure of the lumped leakage inductance and stray capacitance of the high-voltage transformer is presented and discussed in detail considering its iron and copper losses. Furthermore, the leakage inductance and the stray capacitance existing in the high-frequency high-voltage transformer are exactly confirmed on the basis of experimental results.
