Würth Elektronik adds dc ripple bias modelling to its RedExpert on-line power analysis tool. “It is a well-established but little understood fact that ac core losses increase when the ac ripple is dc ...

Stockton, Calif. — West Coast Magnetic has introduced the 307 series of power inductors that can handle very high DC currents and high AC ripple currents from 60 Hz to 500 kHz. The power inductors ...

Green energy applications such as hybrid vehicles, wind energy, and solar energy stand to reap big benefits from regulated electronic power conversion common to switch-mode power supplies (SMPS).

The design trade-offs that must be addressed during the design of a DC-DC converter circuit are simplified by integrating the inductor into the power management device. This article focuses on the ...

In last month's article, it was found that the right-half-plane zero (RHPZ) presence forces the designer to limit the maximum duty-cycle slew rate by rolling off the crossover frequency. This is ...

This course covers the analysis and design of magnetic components, including inductors and transformers, used in power electronic converters. This course assumes prior completion of ECEA 5700: ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...
