1. An interleaved converter, comprising: a plurality of LLC power channels having a power input provided by a respective power source; and a compensation controller configured to actively adjust said power inputs to match output voltage and current levels for a given load condition and a common operating frequency of said plurality of LLC power channels, wherein said compensation controller is configured to adjust said power inputs by controlling said power sources based on a power source output voltage received at said compensation controller directly from each of said power sources wherein said compensation controller is configured to adjust said power inputs by controlling a first power source of said power sources using a first modulator in said compensation controller and controlling a second power source of said power sources using a second modulator in said compensation controller.
