Bi-Directional Flyback Dc-Dc Converter For Battery System Of The Dc House Project, Austin J. Luan Jun 2013

Bi-Directional Flyback Dc-Dc Converter For Battery System Of The Dc House Project, Austin J. Luan

Master's Theses

The DC House project strongly relies on renewable energy sources to provide power to the house for various loads. However, when these sources are unable to provide power at a certain time, a back-up energy source from a battery must be readily available to fulfill the house’s power needs. This thesis proposes a bi-directional flyback power converter to allow a single-stage power path to charge the battery from and to discharge the battery to the DC House 48 V system bus. The design, simulation, and hardware prototype of the proposed flyback bi-directional converter will be conducted to demonstrate its feasibility. …
