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 ...

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 ...

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

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 ...

In the race for ever-improving technology, there are two related technical capabilities that drive our world forward: speed and size. These are related, as the smaller a device is, the less distance ...

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 ...

For the PDF version of this article, click here. In all switching regulators, the inductor is used as an energy storage device. When the semiconductor switch is on, the current in the inductor ramps ...
