Electric motor efficiency depends upon power factor - Part 2 Design How-To 10/16/2009 1 comment Electric motor power efficiency has taken center stage. Individuals, corporations, and governments are increasingly interested in saving power, and we now have the technology that can make it possible. In this second part of a two-part series, Actel shows you how to improve your design's power efficiency using active power factor correction and other techniques.
Electric motor efficiency depends upon power factor - Part 1 Design How-To 10/13/2009 2 comments Electric motor power efficiency has taken center stage. Individuals, corporations, and governments are increasingly interested in saving power, and we now have the technology that can make it possible. Advances in motor control algorithms and cost-effective electronic components for implementing motor drives are creating a revolution in virtually every electric motor market and this article from Actel shows you how to design with this in consideration.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
