| Abstract: | Two-stage Bi-directional DC/DC converter which was composed of Buck/Boost BDC and bi-directional Half-Bridge DCT was described , a novel reactive -soft -switching boost converter was also introduced. An experimental prototype of bidirectional DC/DC converter controlled by DSP is designed. A novel control scheme adopting one port voltage regulated and another port current regulated is proposed to realize the energy conversion in bi-directional freely. In the last, experimental waves verify the theory. |
