LED elements always require some electronic ballast that may consist of a primary power supply and a number of secondary dimmers for light regulation. These circuits can be implemented as DC/DC converters. In the paper buck and boost dimmers are investigated from the point of view of their weight and size, that are close related to their losses. The analysis is provided for various modulation techniques and configurations of the converters. The above mention converters are investigated analytically, through simulation and experimentally.References
