Abstract
A conversion system includes a conversion circuit coupled to multiple cells for generating multiple sampling signals indicative of the cell voltages of the cells respectively. Each sampling signal is with respect to the same reference level. In addition, the conversion system includes a compensation circuit coupled to the conversion circuit for generating a compensation current that flows through at least one cell of the multiple cells via the conversion circuit for balancing the currents respectively flowing through the cells.
