"Synthesis of Input-Rectifierless AC/DC Converters"

This paper presents the basic construction procedure of creating ac/dc converters out of simple dc/dc choppers. the analysis of the rectifierless ac/dc presented as well. It is shown that two separately controlled dc/dc converters are sufficient for producing a regulated dc output and shaping the input current, from an ac voltage source, without the need for input rectifiers. Some design constraints are discussed, emanating from the limitation of the conversion ratios that can be achieved by particular dc/dc converters. Selected topologies are verified experimentally. This kind of rectifierless converters find applications in airborne power supplies where zero-crossing distortions are significant.
