Testing and Measurement Challenges for State-of-the-Art EV Powertrains [Expert View]

January 23, 2023 by Uday Deshpande

Electric vehicles (EVs) are here to stay. Whether it be due to environmental concerns, oil supply issues, gas prices, or governmental mandates, almost every traditional car manufacturer is manufacturing either EVs or hybrid EVs (HEVs) along with the sizeable number of startups. What was perhaps a megatrend a few years ago, is mainstream automotive products today. For more … [Read more...] about Testing and Measurement Challenges for State-of-the-Art EV Powertrains [Expert View]

A Proprietary ZVS-Based Approach Delivers High Efficiencies at Light Load With Half the Components of Conventional Designs

January 23, 2023 by Igor Spinella

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

Assessing SMPS Voltage Regulator Dynamics From Output Impedance

March 1, 2021 by David Bourner

Image of a power button.

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
