摘要： Some embodiments are directed to a three-phase power converter for converting power between a power grid network and a battery that includes a three-phase grid transformer, a three-phase switching converter for coupling to a positive terminal of the battery, a first, second and third series inductors coupled between the three-phase grid transformer and the three-phase switching converter, a control circuit configured for controlling a first, second and third phase differences between first, second and third time-periodical power grid voltage signals provided by the grid transformer and first, second and third converter time-periodical voltage signals provided to the switching converter such that the first, second and third time-periodical power grid voltage signals and first, second and third converter time-periodical currents are in phase. The three-phase grid transformer provides electrical isolation between the power grid network and the battery.
