Keynote Speech: High Power, Voltage, and Frequency Dual Active Bride Design and Applications
Abstract: Dual Active Bridges (DAB) and isolated DABs are finding new applications for power conversion in renewables, energy storage, electric vehicle charging, DC energy systems, and grid-tie systems. An isolated DAB is a Solid State Transformers (SST) that can add flexibility, controllability, and reliability to existing electrical distribution systems. Major elements of a DAB are two power converters and a high frequency transformer. Power electronic switching devices with higher voltage and power ratings have become available in recent years. This availability has enabled development of high power isolated converters that are building blocks for future smart and efficient electrical distribution systems. In this talk, the design and development of high frequency transformers for high power and medium voltage are discussed. Several control methods for DABs including phase-shift, duty ratio, and triple phase shifts are discussed to control the power flow. Methods are discussed to minimize the RMS current, reduce reactive power transfer, and minimize converter loss. Applications of DABs for electric vehicle charging and solar PV systems are demonstrated.
