Sinewave Peak Pulsing Circuit for Rotoverter by Konehead

Here is way to charge a battery from a rotoverter AC motor, the pulsing to the charge battery only occurs at the peaks of the sinewave feeding the AC motor, which makes it "non-reflective" to the amperage draw of the motor while charging the charge battery.
