In order to perform this harmonic reduction, a pure sine wave must first be applied to the Class-D amplifier system. Using the ternary modulated bitstreams described earlier, two pulse density ...

With the increasing popularity of alternate power sources, such as solar and wind, the need for static inverters to convert dc energy stored in batteries to conventional ac form has increased ...

The construction of a PERIODIC signal on the basis of Fourier coefficients which give the AMPLITUDE and PHASE angle of each component sine wave HARMONIC. These coefficients are obtained through ...

Mention the term “power quality” when troubleshooting in an electrical setting, and fear/intimidation almost inevitably set in — even amongst the most seasoned engineers and electricians. By their ...

In my seminars I often talk about the importance of understanding at least a little electromagnetics theory, even for purely firmware people. But the subject is hard to understand and sometimes harder ...

The SLAC National Accelerator Laboratory, Menlo Park, Calif., is home to a 2-mile-long linear accelerator — the longest linear accelerator in the world. This multipurpose laboratory for astrophysics, ...

Fellow writer Charles S. “Buc” Fitch penned a multi-part series on backup power generators in the the Feb. 7, April 18, June 13 and Aug. 8 issues of Radio World Engineering Extra. (Read them at ...
