<p>An active rectification system includes an active rectifier (102) that converts an alternating current (AC) input to a direct current (DC) output. The active rectifier includes a plurality of switching devices (S 1 , S 2 , S 3 ) and at least a first output capacitor (C 1 ) and a second output capacitor (C 2 ) connected at the DC output of the active rectifier. A controller (101) includes a DC output regulation portion and an output capacitor balancing portion, wherein the DC output regulation portion monitors the DC output and in response generates control signals for regulating the DC output to a desired value. The output capacitor balancing portion monitors first and second output capacitor voltages associated with the first and second output capacitors, respectively, and generates an accumulated adjustment value that modifies the control signals provided by the DC output regulation portion to balance the first and second output capacitor voltages.</p> |
