A Proprietary ZVS-Based Approach Delivers High Efficiencies at Light Load With Half the Components of Conventional Designs
The ac–dc power supply units providing isolated, regulated outputs operating above 100 W typically require some form of input active power factor correction (PFC) [1] . To achieve this, a popular solution is to combine a boost PFC input stage with an “LLC” converter which isolates and controls the dc output voltage. However, a new, innovative single-stage technique for … [Read more...] about A Proprietary ZVS-Based Approach Delivers High Efficiencies at Light Load With Half the Components of Conventional Designs
Wide Bandgap-Based Power Electronics for Aerospace Applications
Aerospace applications are not new but potentially the final frontiers for power electronics research and developments. On the aviation side, because of the need for fuel saving and greenhouse gas reduction, more electric aircraft (MEA), unmanned aerial vehicles (UAVs), electric vertical take-off and landing (eVTOL) aircraft, and future hybrid and turbo electric propulsion call … [Read more...] about Wide Bandgap-Based Power Electronics for Aerospace Applications
