At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...

Power Factor (PF) is a measure of how a load draws power from the source. When the current phasor leads the voltage phasor, PF is leading and when the current phasor lags the voltage phasor, PF is ...

The proliferation of end-use electrical and electronic loads in customer facilities — residential, commercial, and industrial — is not slowing down. Despite economic pressures, utility customers are ...

The FN5040HV series of sine-wave filters from Schaffner converts the rectangular PWM output voltage of variable-speed drives into a smooth sine-wave voltage with low residual ripple of less than 5% ...
