Abstract
In an upconverter comprising a choke, a switching element and a diode, the switching element is controlled in such a way that the time interval during which the switching element is non-conducting is proportional to the time interval during which the diode is conducting. The upconverter has a high power factor for a wide range of the amplitude of the line voltage and a wide range of power taken at the output of the upconverter.
