Abstract

The present disclosure relates to a switched mode bidirectional AC-DC converter comprising: an AC side circuit comprising at least two AC power switch pairs comprising a diode and an active switch arranged in parallel; a DC side circuit; a first coupling circuit between the AC side circuit and the DC side circuit; a second coupling circuit between the AC side circuit and the DC side circuit, wherein said first and second coupling circuits comprise at least one further power switch pair comprising a diode and an active switch arranged in parallel; and a control circuit configured to operate the switched mode bidirectional AC-DC converter in four different operation modes corresponding to combinations of polarity of the AC voltage Vac and the AC current lac by enabling only one of the first and second coupling circuits in each operation mode, the control circuit further configured to operate the switched mode bidirectional AC-DC converter in a normal mode and a power factor correction mode. The present disclosure further relates to a method for operating a switched mode bidirectional AC-DC converter in four operation modes.
