Full-Bridge Fault- Tolerant Isolated DC–DC Converters: Overview of Technologies and Application Challenges
Nowadays, energy generation is on the path from centralized to distributed generation paradigm to improve the efficiency and resilience of power systems. One of the major developments in the energy sector was the introduction of dc microgrids that facilitate direct integration of energy sources, storage, and dc loads. Also, most consumer and industrial devices are naturally dc … [Read more...] about Full-Bridge Fault- Tolerant Isolated DC–DC Converters: Overview of Technologies and Application Challenges
Charging Electric Vehicle Batteries: Wired and Wireless Power Transfer
Due to the environmental concerns about CO2-caused global warming, policymakers are pushing electrified vehicles (EVs) to reduce these emissions. For passenger vehicles only, the electrified fleet is forecasted to reach 80 million in the U.S. and 500 million globally by 2040. Key enablers for such rapid EV adoption include the improvement of battery energy density, lifespan and … [Read more...] about Charging Electric Vehicle Batteries: Wired and Wireless Power Transfer
