Abstract
A method for cell voltage balancing is disclosed. A plurality of cells is coupled to a plurality of cell interface circuits, and the cell interface circuits are driven with a balancing transformer such that a balancing current flows between the cell interface circuits. Control gates of the cell interface circuits are driven with a gate drive transformer such that two adjacent circuits of the cell interface circuits are activated with opposite phase.
