A system 100 includes a plurality of units U 1 ,U 2 ,U 3 . Each of the plurality of units U 1 ,U 2 ,U 3 has an energy storage element B 1 ,B 2 .B 3 , a branch switch S 1 ,S 2 ,S 3 and a branch diode D 1 ,D 2 ,D 3 , which are connected in series. The system 100 further includes a transformer 102 which has a primary side and a secondary side and functions as an equalizer for at least one of charging and discharging the energy storage elements B 1 ,B 2 ,B3 to achieve equalization. The plurality of units U 1 ,U 2 ,U 3 are connected to the primary side through a control switch S N+1 and isolated from a secondary circuit 104 connected to the secondary side. |
