Abstract
In order to regulate the dose rate, the pulse-pause ratio of the inverter is changed. For this purpose, the regulator can be designed in such manner that, within a predetermined range of the error signal it changes this pulse-pause ratio via a regulating unit and, upon transgression of this range, changes the peak voltage supplied to the inverter via a regulator unit upon constant maintenance of a minimum pulse-pause ratio.
