Abstract
A rectifier comprising a preregulator ( ) and a DC/DC converter ( ) is disclosed, comprising means for controlling the output power P from the DC/DC converter in dependence of the input power to the preregulator. A method of controlling such a rectifier by controlling the output power P in dependence of the input current I is also disclosed. This ensures that the output power from the rectifier is never higher than what the preregulator can supply. As a result the rectifier according to the invention may be used at any power level and any input conditions. The output power P may be controlled by controlling the output current I from the DC/DC converter.
