Abstract
The present invention relates to a voltage converter comprising a primary side which has a full bridge device which is configured for the purpose of receiving a first DC voltage from a voltage source at a first amplitude and to transmit same to a primary coil arranged in the primary side, comprising a control unit which is designed for the purpose of controlling the full bridge device using PWM signals having phases shifted counter to one another, wherein the control unit is configured to detect an asymmetry in the current supplied to the primary coil based on a current profile in the primary coil, wherein the control unit is designed to compensate for a detected asymmetry by adjusting the PWM signals. The present invention further relates to a corresponding method.
