B&K Precision Introduces AC Sources With 3-Phase Capability and Up to 3000 VA Per Phase

B&K Precision announced the 9830B Series programmable AC power sources providing high performance and low total harmonic distortion in a 3U form factor. Offering 2000 VA or 3000 VA models, the new 9832B and 9833B provide the ability to connect three instruments to create a 3-phase AC power source using the convenient 3-phase kit (TL983P-KIT) option. The adapters included in the kit provide synchronization and timing signals to create a 3-phase system, with voltage, phase, and frequency parameters controllable from the front panel or remotely using the provided PC software.

Infineon OptiMOS Power MOSFETs with Highest Power Density and Efficiency

Available in space-saving SuperSO8 packages, Infineon's OptiMOS 3 and 5 best-in-class (BiC) power MOSFETs enable higher power density in addition to improved robustness compared to former models. With the new components, system costs are reduced while the overall performance is increased. The OptiMOS power MOSFET devices from Infineon are designed for synchronous rectification in power supply applications and are the ideal choice for other applications such as low voltage drives and Class D amplifiers.

A Power Supply Spreadsheet

This article describes a spreadsheet program for designing low-voltage power supplies using common IC three-terminal regulators. The spreadsheets are in standard Excel format, and should work in just about any spreadsheet program. Each file has two main pages: one for use with common variable-output regulator chips, the other for fixed-output devices. This article was published in audioXpress, March 2010.

An Alternative to Linear Regulators: Equivalent Power-Line Ripple Rejection with Less Power Dissipation

In this article for audioXpress, Bill Reeve discusses “An Alternative to Linear Regulators.” A project were he searches for equivalent power-line ripple rejection with less power dissipation, using a source follower-based (SFB) low-pass filter. Because no one wants to listen to an audio amplifier that hums. This article was originally published in audioXpress, April 2014.
