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

Power Electronics Hardware Design for Manufacturability
With a small, diverse team of engineers, Magna-Power Electronics can offer over 160,000 different configurations of programmable power supplies and electronic loads, spanning current levels up to 10,000 Adc, voltage levels up to 10,000 Vdc, and power levels up to 3,000 kW. This feat is made possible through tightly integrated engineering and manufacturing teams, minimizing … [Read more...] about Power Electronics Hardware Design for Manufacturability
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
