Here's an article describing a simple bidirectional buck/boost DC/DC converter design. It's not a complete design, but give enough information to give people an idea of how active balancing devices work.
If you're going to design your own active balancer, this is a good place to start.
Note that it is NOT isolated, and cannot be used as-is in series battery circuits. Isolation would be achieved by using a transformer in place of L1.
