摘要
Electronic ballasts and buck-boost DC-DC converters therefore are presented with a buck converter (210) with two switching devices connected with two capacitances (C1, C2) and two diodes (D1, D2) to limit the individual switching device voltages to around half the converter DC input voltage or less.
