Abstract
A power conversion method is disclosed. The method includes 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. Operating the SR converter includes regulating a voltage level of the DC link voltage dependent on a DC link voltage reference, and the at least two different operating modes of the SR converter include a buck mode and a series resonant mode.
