High-Voltage Capacitors: Design and Testing

March 9, 2010 9:23 am | by Joe Moxley, Senior Engineer, Custom Electronics, Inc. | Comments

There are many industries that depend on the proven design concepts that require high voltages to operate. Radar, X-ray machines, traveling wave tubes, down-hole logging, particle accelerators, aerospace ignition systems, partial discharge detection, power utilities and welding equipment are some examples.

Simplify Power Designs with an Innovative MOSFET Package

March 4, 2010 10:32 am | by Hawk Lee, Jingen Qian & Kim Norton, Vishay | Comments

A major challenge facing power engineers today is how to overcome a reduction in board space for the power circuitry in commercial electronic products. A quick walk through any electronics retail store will reveal that personal computers have become smaller and even miniaturized which is a trend for many other types of electronic devices.

Discrete Components Optimize Medical Equipment Performance and Reliability

March 4, 2010 10:16 am | by Steve Wade, VP of Sales and Marketing, TT electronics | Comments

Medical electronics applications require components that are smaller, more robust, and highly versatile, particularly as medical equipment becomes increasingly portable. Because medical systems often use discrete electronic components in their circuit designs, passive components are critical to optimizing performance and reliability.

MOSFETs Provide Efficient Operation for Battery-powered “Green” Products

March 4, 2010 9:33 am | by Kevin Turchin, FAE Manager, ROHM Semiconductor | Comments

Portable products increasingly rely on a single 3.7V Li-Ion battery for the energy source. For these and other low-voltage applications, lower gate voltage power MOSFETs improve the efficiency for extended battery life and reduce the heat dissipation involved in switching the loads. In addition, they simplify the design of numerous control functions by allowing direct control / drive.

Partial Networking: In-Vehicle Networks Can Reduce Costs and CO2 Emissions

March 4, 2010 6:40 am | by Holger Huber, System Marketing Manager In-Vehicle-Networking, NXP Semiconductors | Comments

In the past, electronic control units (ECUs) in automotive applications were connected by individual signal wires. However, today, close to 100% of the ECUs are connected by bus systems such as LIN, CAN and FlexRay. This yields significant advantages, including improved data availability, straightforward wiring and standardized interfaces.

Power politics

March 3, 2010 12:26 pm | Comments

I recently had the great honor of moderating the Smart Grid Rap Session at this year’s Applied Power Electronics Conference (APEC). It brought home to me that in addition to the technical challenges facing the power industry, there are also political issues that must be addressed as we move forward. The old political arguments around power revolved around NIMBY issues about the location of power plants...

Telematic Antenna Testing

March 2, 2010 8:35 am | Comments

Today’s automobiles have a wide variety of RF systems with antennas on them for Sirius and XM radio, collision avoidance radars, the Global Positioning System (GPS) and other systems. Conventional test facilities can only perform terrestrial directed pattern measurements of the antenna on the automobile.
