Wireless power systems are getting popular with the improvement in the technology not just because it is a fancy and cool conception but also because it is more convenient and safer in some applications. For example, this project aims to help high power data center design to be changed to wirelessly powered center to provide a safe and hands-on work environment even under different load conditions. Thinking of the …

Analysis, Design And Implementation Of A Resonant Solid State Transformer, Mohamad Zouheir Sabbah
Theses and Dissertations
This thesis discusses the design of a full-bridge resonant LLC Solid State Transformer. The proposed topology uses a high-frequency transformer which helps minimizing its cost and size, and enables operating at varying load conditions. By using a resonant circuit, soft switching is achieved. Commutation techniques are discussed, namely ZVS and ZCS. Both concepts are applied on different legs of the H-bridge. Pulse frequency modulation (PFM) and Phase Shifting Modulation (PSM) are utilized to control this resonant converter. One of the requirements of this work is to achieve a tightly regulated DC bus voltage. This was shown to be achieved using …
