Advanced Inverter Interactions With Electric Grids
The evolution of advanced inverter-based resources (IBR) is closely coupled with the growth of their applications in electric power networks. Most applications of inverters during this transition were grid-following (GFL) inverters. As IBRs gradually displaced rotating synchronous generators in electric power grid applications, issues such as the behavior of low-inertia grids, … [Read more...] about Advanced Inverter Interactions With Electric Grids
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

Assessing SMPS Voltage Regulator Dynamics From Output Impedance
Stable operation of a SMPS (switching voltage power supply) hinges on action within the feedback control and compensation network. The way in which the regulator performs is also influenced by the nature of filters attached on either side of it between the source and load. This article shows how stability can be assessed using only knowledge of the system’s output impedance. … [Read more...] about Assessing SMPS Voltage Regulator Dynamics From Output Impedance
