BART, AC Transit, Muni and Caltrain will receive a $590 million loan from the state to fund operations for the coming year.

Abstract: The three-phase grid-tied pulsewidth modulation (PWM) converter in the dc bus system is utilized to achieve energy conversion. Due to the influence of factors, such as time and temperature ...

Erik Kroon discusses the need for calibrating AC power instruments at very high frequencies, to 100 kHz. In the engineering world system performance can only be properly improved and built on through ...

The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source,” an intriguing programmable constant current source which elicited a lively conversation in its ...

This basic non-contact transducer is often used to measure AC currents. Accurate measurement of static and dynamic current flow in a conductor is a common requirement in many circuits and systems.

The AC magnetic field response of the superparamagnetic nano-ferrofluid is an interplay between the Neel and Brownian relaxation processes and is generally quantified via the susceptibility ...

A new approach to low-level sourcing and measuring for material or device characterization This video examines the unique measurement capabilities of the modular M81-SSM synchronous source measure ...
