Don’t Overlook These Keys to Optimized Converter Performance

Len Crane, Senior Technologist, Coilcraft

Inductors function as circuit elements by reaction to current flow in the windings. Inductors are fundamentally current-driven devices, and anyone who has designed a dc-dc converter knows power inductor datasheets are covered with Irms and Isat current ratings. Picking a power inductor is all about current ratin

What is Actually Needed to Ensure Efficient Charging of EVs?

Ralf Hickl, Product Sales Manager Automotive Business Unit (ABU) at Rutronik

For BEVs (battery-electric vehicles), low power (kWh/km) is essential. Its calculation often not only includes the power from the battery but also the power required by the AC Wallbox to charge the battery. Charging losses in the onboard charger (OBC) therefore affect this figure directly. To ensure a low pow
