Abstract

A multiple output rectifier achieving effective supply of power to a plurality of loads. The multiple output rectifier converts an AC input signal into a first rectified output signal and a second rectified output signal, wherein the AC input signal has a fundamental period dividing into a first partial period where an AC current flows in a first direction and a second partial period where the AC current flows in a second direction being a reverse direction to the first direction. The multiple output rectifier includes a first input terminal and a second input terminal different from the first input terminal for input of the AC input signal. The multiple output rectifier further includes a common output terminal, a first output terminal, and a second output terminal. The common output terminal, the first output terminal, and the second output terminal are decoupled from each other for operation in a multiple output operative mode. In the multiple output operative mode and during the first partial period the multiple output rectifier is adapted to maintain polarity of the AC input signal and to transfer it to the second output terminal and the common output terminal as the first rectified output signal. Further, in the multiple output operative mode and during the second partial period the multiple output rectifier is adapted to reverse polarity of the AC input signal and to transfer it to the first output terminal and the common output terminal as the second rectified output signal. The multiple output rectifier may also comprise a switching circuit component between the first output terminal and the second output terminal to change the multiple output operative mode to a full bridge operative mode and vice versa.
