The paper presents a novel converter for a medical X-ray machine application. A resonant, current fed inverter is proposed. The high voltage transformer step up ratio is kept very low to reduce the effects of its leakage inductance and other nonidealities. Moreover this leakage inductance and the parasitic capacitance of HV transformer and switches are used as resonating components for attaining a soft switched conversion. The switches are soft switched with ZCS, which works over a wide load range. A set of Cockroft Walton multiplier is employed on the secondary side of the transformer accomplishes the final output. The converter operates at 100 kHz frequency with overlap time switching to achieve 100kV and 2.5 RNA required by the X-ray machine. A very systematically elaborated analysis for selection of every discrete component in this particular topology is discussed in this paper. © 2016 IEEE.
