Abstract
The invention relates to a lighting system comprising a parallel resonant converter comprising an input node for receiving a bus voltage an output node a half bridge comprising a first switch coupled between the input node and a switching node and a second switch coupled between the switching node and a return node. The parallel resonant converter further comprises a controller adapted to provide a first control signal to the first switch and a second control signal to the second switch an inductor coupled between the switching node and the output node. The lighting system further comprises a load comprising a first load part, the first load part comprising a first lighting load a capacitor coupled in parallel with the first lighting load and a second lighting load coupled in anti-parallel with the first lighting load, wherein the load further comprises: a third lighting load and a fourth lighting load, coupled in anti-parallel with the third lighting load, wherein the third lighting load and the fourth lighting load are coupled in series with the first load part.
