Abstract
A resonant power converter is provided. The resonant power converter comprises a balancing circuit for balancing the voltage in a feeding connection. The balancing circuit comprises: a first positive control means in series with an inductor, wherein the first positive control means and the inductor is coupled between the positive DC conductor and the feeding connection, and a second negative control means in series with the inductor, wherein the second negative control means are coupled between the negative DC conductor and the feeding connection. The first positive and second negative control means are adapted to be alternatingly switched on and off for balancing the resonant power converter, such that the voltage in the feeding connection is substantially the mean voltage of the positive DC conductor and the negative DC conductor.
