<p>A Parallel Charge, series discharge method and apparatus for power factor correction and improved efficiency comprising an energy source (20), two (or more) impedance(s) (Z1 and Z2) capable of storing and delivering electrical energy, a switching circuit having one position so that impedance(s) charge in a parallel mode with a fraction of the electrical energy incoming from one (or more) (20) rectified AC input generator(s), and another position so that impedance(s) discharge some of the electrical energy stored into the load (30), the switch having a frequency and duty cycle so that the input current rectified waveform from the energy source will approximate the voltage rectified waveform from the energy source (20).</p> |
