Scientists in the Middle East have developed a series active filter to improve power quality in grid-tied PV systems, consisting of an inductor, two capacitors, and four transistor-diode pairs. The ...

If you're responsible for maintaining quality power at a commercial facility and you've got a problem with harmonics, your best bet is to install a series of active filters. Opting for such filters ...

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, ...

Power quality of the system will be affected due to the increasing use of power electronic equipment and nonlinear loads. Active Power Filters (APF’s) are effective in mitigating line current ...

A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well. The nature of the EMI problem in ac-dc supplies and its ...
