Abstract
A bi-directional converter offers power conversion between both 270 volts to 28 volts and 28 volts to 270 volts. The converter utilizes common magnetic components such as a transformer and a filter inductor and dual function built/in diodes across transistors. The converter also utilizes a bridge converter, a push-pull converter, and a boost converter.
