San Jose, Calif.—Specialized IC supplier Mixed Signal Integration has a nifty 16-pin CMOS chip that can measure THD (total harmonic distortion). The MSTHDA analyzer IC is a single-chip 1/6th ...

Researchers in Malaysia have published a study of total harmonic distortion (THD) reduction techniques in PV systems and claim to have found an holistic and systematic approach. The paper Advances in ...

A network of sensors has begun providing what may be the first collection of utility customer readings of one critical measure of power quality reaching U.S. homes. Some 1-million plug-in devices ...

A couple weeks ago I built a simple 1KHz 6Vpp Sine Wave Generator from a handful of opamps and passives I had laying around. You can check out that project here. I thought it would be fun to quantify ...

Arteche PQ, Inc. has introduced a complete range of active harmonic filters. This new filter product line achieves 5% total harmonic current distortion (THD) by monitoring the flow of harmonic ...

It is estimated that there will be more than 1,675,000 distributed renewable generation inverters connected to electrical grids around the world in 2030. But there is an element associated with these ...

The power quality of electrical distribution systems has a drastic effect on power regulation and consumption. Power quality includes all aspects of events in the power system that deviate from normal ...

Total harmonic distortion (THD), is a popular measure of nonlinearity of a device. Learn about the considerable flexibility in defining THD while providing a relatively simple way to orchestrate all ...
