Abstract

A method of operating a power converter arrangement includes a dc link and a dc load/source. An active rectifier/inverter is connected to the dc link and is adapted to provide a variable dc link voltage V\ between maximum and minimum limits. An interleaved buck converter having a plurality of converter circuits is connected between the dc link and the dc load/source Each converter circuit includes a first switch, a second switch and a reactor. The power converter arrangement is controlled according to a method where one or more null values of dc link voltage are determined with reference to the voltage V2 across the dc load. If a null value of dc link voltage is between the maximum and minimum limits, the active rectifier/inverter is controlled to provide a dc link voltage that is substantially the same as the null value of dc link voltage.
