| Abstract |
A scalable parallel bidirectional DC-DC converter system, which enables efficient seamless controlusing an H-bridge topology, was developed and evaluated. Although the unified control structure issimple, four drive-mode, both charge and discharge with buck/boost, can be handled. The proposedsystem was extended for use in simple parallel converter management. This scheme achieves highefficiency over a wide load range, especially for light loads. The only hardware required is a powerline and communication cable connection. All other functions are provided by software and operateautonomously. A 5-kW prototype converter was constructed and evaluated, and a four-unit parallelconverter system was tested and confirmed to work well, changing load between 20-kW discharge and20-kW charge. |
