  • Grid-tied inverter, inverter arrangement, and method for operating an inverter arrangement
    Patent number: 9917532
    Abstract: A grid-tied inverter for supplying current to a power supply system includes an output bridge arrangement that is actuated via a pulse width modulator, wherein switching times of the output bridge arrangement are determined by using a periodic auxiliary signal, wherein the frequency of the periodic auxiliary signal varies according to a prescribed periodic wobble signal. The inverter further includes a synchronization unit configured to provide phase synchronization of the auxiliary signal to the power supply system, wherein the synchronization unit is configured to adjust a prescribed phase offset of the periodic auxiliary signal in relation to a phase of the power supply system, and a further synchronization unit configured to provide phase synchronization of the periodic wobble signal to the power supply system.
