DC capacitor balancing
Methods and devices for balancing voltages of capacitors in an electronic circuit are provided. The device includes a chopper circuit having a chopper inductor. Further, the chopper circuit may detect voltages across capacitors as well as an output current of the electronic circuit. In addition, the device may include a chopper control unit receiving the output current then generating a signal representing charging of the chopper inductor based on the output current. Also, the chopper control unit may receive the voltages across the capacitors and detect an imbalance between the voltages based on a polarity of the output current. Additionally, the chopper control unit may transfer of charge between the two capacitors, using the chopper inductor. Further, the chopper inductor is substantially discharged, during the transfer of charge between the capacitors.
