摘要：This study proposes an automatic cell-to-cell equaliser to balance the battery voltages in series-connected battery strings. In the proposed equaliser, each cell needs only one MOSFET, and the adjacent cells share the transformer winding. The voltage balance is automatically realised by using a pair of complementary control signals with a fixed duty cycle. What's more, no sensing circuit is required. Consequently, the proposed equaliser is cost-effective and easy-to-realise. The circuit topology and operating principles are firstly presented. Then the voltage balance analysis is given in detail. Moreover, a design guide is also given by considering four lithium-ion cells. Finally, the validity of the proposed equaliser is verified by experimental results.
