“…Single-stage topologies for three-phase ac/ac conversion transfer power directly through the high-frequency transformer without any intermediate dc link. The topologies presented in this section include direct and indirect isolated matrix converters [60]- [62], three-phase ac/ac flyback converter [63], Dyna-C converter [27]- [30], AC-Link converter [42], [64], [65], and partial resonant ac link converter [25], [26].…”

My journey of doctoral study at Georgia Tech has never been short of amazing experiences and great challenges. Without the inspiration, support, and advice from many people, these challenges could never have been conquered and no milestones of the journey could have been reached. This thesis is a result of the many experiences that I gained from these people, to whom I would like to express my acknowledgements.First and foremost, I would like to extend my deepest gratitude to my advisor, Dr.Deepak Divan, for his encouragement, inspiration, and guidance throughout my doctoral study. Working on several projects under his support helped me to obtain valuable skills and confidence. He has been always instrumental in giving prompt suggestions whenever I sought guidance from him. The most valuable experience I learned from him is to know the importance of identifying problems, rather than just understanding how to solve them.It is my great honor to be one of his students and to be part of the newly-established Center for Distributed Energy at Georgia Tech that is directed by him. I sincerely believe that the fruitful experience I gained from him will continuously benefit me during my coming career as an engineer.Further, I would like to extend my sincere thanks to my committee members Dr.

“…Those converters include a high frequency transformer, acting as a dc current source, and use charge control to regulate the output current, as discussed in [16] and [17]. The high-frequency transformer, an energy storage component for power conversion, has higher reliability and longer life than electrolytic capacitors used in VSCs [15]. Moreover, comparing with topologies described in [13] and [14], it has only two conversion stages and fewer semiconductor switches.…”

“…It can realize bi-directional power conversion with galvanic isolation, low current distortion, unity power factor, and support multiple ac or dc ports simultaneously. Various topologies described in [9]- [15] have been developed for power conversion for dc, single-phase ac, and three-phase ac systems. However, some of their drawbacks include poor power factor, large filter size, multiple conversion stages, or operation limited to low power levels.…”

Techniques for operating at medium voltage using semiconductor devices of lower rating are well known in the industry and academia. These techniques range from device to converter stacking. Dynamic current (Dyna-C) topologies are a new class of converters that is able to provide fast dynamic control with bi-directional power flow and galvanic isolation. These converters can interface with dc, single-phase ac, and/or three-phase ac systems. Scaling to medium voltage can be achieved via modular stacking of lower voltage cells. However, voltage and power balancing between the cells is challenging and complex due to the differences in control dynamics and low energy inertia of each cells. This paper presents a control strategy to provide stable and well regulated voltage across each of the cells in a stacked Dyna-C configuration. Simulation results are provided to verify the control strategy.
