Abstract
A circuit arrangement provided with a switch mode power supply energized with a pulsatory input current generated by means of high-frequency switching of the main switching means HS (3) provided in turn with a drive circuit (6) having at least drive switching means SS (60) and connected to a return current line (7). A self-inductance element (61) is included in the drive circuit, preferably between the main switching means HS and the drive switching means SS. This arrangement results in a rapid level shifter of compact construction.
