Microchannels Take Heatsinks to the Next Level

The convective performance of microchannel cooling systems for high-power electronics can be improved to the point where the total thermal resistivity is no longer dominated by the heatsink....

SPICE3 Enables Accurate Modeling of Complex ICs

The capabilities of SPICE3 permit the simulation of circuits incorporating the latest ICs by way of special algorithms and modeling techniques....

Digital Bus Makes Current Sharing More Robust

Power supplies in servers, storage and telecom systems often employ redundant topologies. This means that multiple supplies connected in parallel provide...

Voltage Regulators Rev Up PWM-Based Fan Control

The simplest of fan-control schemes an on-off switch is simple but inefficient, because it provides more cooling than necessary most of the time. When...

Motor-Control Technologies Bolster Aircraft Efficiencies

Never before has the aircraft industry focused so much on lighter, more fuel-efficient airplanes. And for good reason: The cost of aircraft-grade fuel...

New Products

Wirewound Inductor Taiyo Yuden's NR8040T series of 8-mm 8-mm 4-mm wirewound power inductors is intended for dc-dc converter choke coil applications. The...

SiC Technology Enables Discrete Revolutions

While silicon carbide (SiC) was once well known as the technology used to implement the first blue light-emitting diodes (LEDs), and is now used as a...

Bootstrap Feedback Linearizes Current Source

Adjustable current sources often exhibit a nonlinear control characteristic, but the inclusion of bootstrap feedback provides an inherently linear control that works well at all levels of output current....

Energy Experts Weigh In On Conservation

Attendees at the recent Power Electronics Technology Conference in Long Beach, Calif., heard two compelling presentations on the subject of energy efficiency....

More Growth and Specialization Loom Ahead for Power Semiconductors

Over the next five years, the power semiconductor market will continue to experience steady growth, with no disruptive device technologies impacting the...

Motion-Control Platform Takes Flight

With the introduction of the IRMCT3UF1 motor-control module, International Rectifier (IR) has taken motor-control technology originally developed for...

Chips Simplify Driving of High-Brightness LEDs

A pair of LED drivers from Maxim Integrated Products provides highly compact and simplified designs for driving the high-brightness (HB) LEDs that are...

Correction

In the October issue of Power Electronics Technology, in a house ad on page 55, we neglected to credit the Darnell Group of Corona, Calif. as the source...
