ABSTRACT:
A stabilized power supply for X-ray tubes having a first rectifier circuit, an inverter circuit comprising main switches, a transformer, a second rectifier circuit an oscillation circuit and an inverter circuit. The power supply includes an auxiliary circuit that can be, driven and is parallel-connected to the oscillation circuit. The auxiliary circuit duplicates changeover switching times of the switches of the inverter in order to limit an overlapping phenomenon that occurs for these switches during the changeover switching operations.
