Abstract

An X-ray source arrangement (10) for generating X-ray radiation (102), a method for operating the X-ray source arrangement (10), and an X-ray imaging apparatus (100) are provided. The X-ray source arrangement (10) comprises an X-ray tube (22), a converter arrangement (16) with an inverter (18) and a resonant converter (20) for providing a source voltage to the X-ray tube (22), a pre-controller (12), and a modulator (14). The pre-controller (12) is configured for determining a reference duty ratio (r, 26) of the resonant converter (20) as a continuous function of time based on a mathematical model of the resonant converter (20), and for providing a control signal (13) correlating with the reference duty ratio (r, 26) to the modulator (14). The modulator (14) is configured for determining a switching signal (15) based on the control signal (13), and for providing the switching signal (15) to the inverter (18) of the converter arrangement (16) for actuating the inverter (18).
