Abstract: This invention relates to an ACDC converter (1) comprising a converter input (3) and a converter output (5), a pre-regulation stage (7) and a DC transformer stage (9) comprising a transformer input stage (11) and a transformer output stage (13). The transformer input stage comprises a double ended converter and there is further provided a controller (17) for providing a control signal to the double ended converter. The controller (17) operates the ACDC converter using burst mode control and by sending control signals comprising pulse sets that are designed to provide substantially zero net magnetising current in the double ended converter. The pre-regulation stage preferably comprises a buck converter which in turn also provides power factor correction to the input of the ACDC converter.

Abstract: The present invention relates to an AC/DC converter (1) of the type having an AC/DC conversion stage (2) and a DC/DC conversion stage (3), the AC/DC conversion stage (2) comprising an input filter stage (4), an input rectifier stage (5) and a tracking boost converter stage. The boost converter stage in turn comprises an input choke (10), a boost diode (16) and a bulk capacitor (17).

The DC/DC stage (3) is arranged to receive the range of voltages from the bulk capacitor (17) and is controllable to provide a desired DC output regardless of the voltage received from the bulk capacitor (17). This is achieved through careful combination of components and use of output feedback control to control the voltage applied to an isolated transformer (41) in the DC/DC stage.
