Electronic equipment and power supplies without any active or passive power factor correction (PFC) circuits have an input current waveform which has a poor power factor and high harmonic distortion.

Passive circuits for power factor correction (PFC) are simple, reliable, robust, and they don't generate EMI [1-4]. Plus, they offer a low-cost alternative for complying with harmonic current limit ...

The circuit was designed to create a classic electronic crossover circuit that will provide a 3-way output on all loudspeakers. Electronic Crossover – an external electronic signal processor that ...
