Abstract
Disclosed is a bi-directional battery power inverter () comprising a DC-DC converter circuit element () to which the battery () can be connected in order to generate an AC output voltage from a battery () voltage in a discharging mode while charging the battery () in a charging mode. The inverter () further comprises an HF transformer which forms a resonant circuit along with a resonant capacitor (). In order to increase the efficiency of said battery power inverter, the transformer is provided with two windings () with a center tap () on the primary side, said center tap () being connected to a power electronic center-tap connection with semiconductor switches () while a winding () to which the resonant capacitor () is serially connected provided on the secondary side.
