Abstract
A galvanically isolated transformer () for energizing a lamp () comprises a primary circuit () including a half-bridge circuit that has two reciprocally clocked switches (), and including an LLC resonant circuit (-). The transformer () further comprises a secondary circuit () including an output () for supplying energy to the lamp (). A control device () is designed to control the half-bridge circuit in accordance with a control variable (ipeak) detected in the primary circuit () in order to adjust a current intensity supplied to the lamp () by the secondary circuit () to a desired value.
