Abstract
The present invention relates to a power converter (1, 1′) comprising an input terminal (+IN, −IN) connected to an input power source, at least an input switch arrangement (T1, T2; T10, T12), and an output terminal (+OUT, −OUT). The input switch arrangement (T1, T2; T10, T12) is arranged to convert the input power, where the power converter (1) further comprises a control unit (P1, N1) that is arranged to control at least the input switch arrangement (T1, T2; T10, T12). The control unit (P1, N1) is arranged to perform said control of the input switch arrangement (T1, T2; T10, T12) in dependence of the efficiency of at least a part of the power converter, the control unit (P1, N1) having information regarding the power at the input terminal (+IN, −IN) and the power at the output terminal (+OUT, −OUT). The present invention also relates to a corresponding method.
