1. A power conversion method, comprising:
operating a PFC converter configured to receive three input voltages and provide a DC link voltage between DC link nodes in one of at least two different operating modes; and
operating an SR converter coupled to the PFC converter via the DC link nodes in one of at least two different operating modes dependent on an output voltage of the SR converter,
wherein operating the SR converter comprises regulating a voltage level of the DC link voltage dependent on a DC link voltage reference, and
wherein the at least two different operating modes of the SR converter include a buck mode and a series resonant mode.
