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