Abstract
Rectifier circuit (600) comprising a pair of input terminals (614, 616), a pair of output terminals (654, 656), and a first circuit (601) interconnecting the pair of input terminals (614, 616). The first circuit (601) comprises an energy storing element (34) and a rectifier bridge (642), wherein the rectifier bridge comprises at least one controllable switching element (645, 647) per bridge branch. An output of the rectifier bridge (642) supplies the pair of output terminals (654, 656) and wherein the at least one controllable switching element per bridge branch is configured to provide a temporary conducting path via the rectifier bridge which substantially bypasses the pair of output terminals (654, 656) and which substantially short-circuits a second circuit (602) comprising the energy storing element (34), the pair of input terminals (614, 616), and an energy source (12) connectable to the pair of input terminals. A converter for synchronized switch harvesting on inductor comprising such a rectifier circuit and a method for rectifying an electrical current generated by an energy source are also described.
