Lifetime-based power routing of smart transformer with CHB and DAB converters

Smart Transformers (ST) are a potential solution for installing intelligent nodes in the electrical distribution grid, which can provide DC connectivity and are capable of providing grid services the traditional low-frequency transformers was not able to provide. However, the reliability of STs is one...

Comparison of voltage control methods of CHB converters for power routing...

Abstract—For Smart Transformers (ST), reliability is one of the major problems when compared to the traditional low frequency transformers. Modular ST with advanced control algorithms could increase the reliability compared to the nonmodular solutions. This could be achieved by distributing differently...

Active thermal control of a DC/DC GaN-based converter

Advanced packaging technologies in Wide band gap devices like GaN avoid wire bonds thereby making the solder joints more susceptible to thermo-mechanical fatigue. To limit the thermal cycling induced failures, an active thermal control scheme using a two step gate driver for a buck converter is presented...

Analysis and design of LCL filter based synchronverter

Synchronverters have gained interest due to their capability of emulating synchronous machines (SMs), offering self-synchronization to the grid. Despite the simplicity of the control structure, the adoption of an LCL-filter makes the overall model complex again, posing questions regarding the tuning...
