Increasing current densities and short switching times in MOSFETs are placing ever greater stress on the dielectric strength of inductors. Molded inductors with a distributed air gap based on iron powder enable high inductance values in the smallest of spaces and thus increase the power density. A new test con

Determination of the Ideal Power Inductor for Energy-Efficient Applications

Alexander Gerfer, Ranjith Bramanpalli, Jochen Baier, Würth Elektronik

Energy-efficient devices are important components for saving resources and protecting the environment. The more efficient the electronics, the longer the battery service life for mobile devices - and in large-scale industrial and server installations with thousands of loads, the energy requirement is markedly re

Advanced packaging methods for modern power supplies

Stefan Preimel, Concept and Application Engineer, Infineon Technologies

No matter the technical innovation or application, all modern technologies have one thing in common; they rely on a reliable, small and high performance power supply to be able to function and meet their specification. As end products become more complex, the design parameters for the power supply become more ch

1.5kW Digital Totem Pole PFC Design for Air-Conditioner Using iMOTION Digital Controller

Wei Wu, Infineon Technologies

A lot of research focuses on bridgeless PFC in order to achieve higher system efficiency compared to traditional boost PFC. Most of the bridgeless PFC solutions suffer from EMI issues, which cause problems in applications where an inverter stage shares the same ground. In this case, the PFC stage generates
