Abstract

The invention relates to a circuit arrangement for operating lamps. The circuit arrangement essentially comprises a full bridge. According to the invention, at least one inductor is connected in series with a full-bridge branch for switching load relief purposes. The circuit arrangement is preferably suitable for operation using a charge pump. PFC is thus achieved in a single-stage arrangement.
