Abstract
The present invention refers to high-voltage generators, in particular to a step-down DC-to-DC converter circuit (buck converter) for supplying a DC output voltage Uwhich may e.g. be used in a voltage supplying circuitry of an X-ray radio-graphic imaging system. According to the invention, the peak value of the buck converter's storage inductor current Iis controlled by a control circuit μC' which regulates the on-time Δtof a semiconductor switch S in the feeding line of this storage inductor L. As a result thereof, an output current sensor CS, which is commonly used in today's buck converter designs, becomes redundant.
