A dimmable electronic ballast for at least one gas discharge lamp, particularly a fluorescent lamp, comprises a power factor correction (PFC), which is supplied with an input voltage, is controlled by a DC link voltage controller, and which serves to create a controlled DC link voltage, and comprises an inverter, which is supplied with the DC link voltage and which supplies the lamp. Dimming values for presetting a set lamp output are fed to the ballast. The DC link voltage controller has different properties at different applied dimming values. |
