摘要： An electronic ballast for a lamp has a DC voltage connection; a switching unit having a supply voltage with the DC voltage connection being coupled thereto, and a first capacitor coupled between the supply voltage connection and a reference potential; an AC voltage connection, at which a voltage can be made available which has at least one AC component. The series circuit includes a first nonreactive resistor and a first diode, as a second nonreactive resistor coupled between the AC voltage connection and the supply voltage connection, a connection point between the first diode and the second nonreactive resistor, and a second capacitor coupled between the connection point and the reference potential. The first capacitor and the second nonreactive resistor are dimensioned such that the average voltage drop across the second nonreactive resistor is greater than or equal to the average voltage drop across the first capacitor.
