When the capacitor is connected in the sinusoidal AC circuit, the maximum voltage and current will have 90 ° phase difference. According to this theory, the C1 and C2 are connected in series to form the difference, and it is more stable than the connection of resistors and capacitors in series. In the circuit, D1 and D2 rectify respectively positive half-wave and negative half-wave of power, and then it is added to the A trigger and C1 or C2 begins charging. Further using W can change the trigger time for shift-phase, as long as the adjustment of W resistance, you can achieve the purpose of changing the output voltage.
