High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.

Most applications that use power factor correction (PFC) are mandated by regulatory requirements like the IEC1000-3-2 harmonic reduction requirement in force since January 1, 2001. The regulation ...

Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...
