Zusammenfassung:	Current arrangement for operating a high intensity discharge lamp or a ultra high pressure discharge lamp, comprising a DC-to-DC converter, a control circuit for controlling the output value of the DC-to-DC converter, and a commutator. The control circuit comprises two control loops, one of which controlling an absolute average value of the lamp current, the other of which controlling and minimizing small variations of the lamp current around a reference value. An adaptive control of the first and second loop controllers can be used to adjust the controllers to changing system dynamics.
