Abstract: Rectifier circuit including a pair of input terminals, a pair of output terminals, and a first circuit interconnecting the pair of input terminals. The first circuit includes an energy storing element and a rectifier bridge, wherein the rectifier bridge includes at least one controllable switching element per bridge branch. An output of the rectifier bridge supplies the pair of output terminals 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 bypasses the pair of output terminals and which short-circuits a series connection of the energy storing element and an energy source connectable to the pair of input terminals. A converter for synchronized switch harvesting on inductor including such a rectifier circuit and a method for rectifying an electrical current generated by an energy source are also described.
