The voltage is rectified by the D10 switching diode and becomes a DC voltage V1.\u00a0<\/span>
V1 divides the voltage between R14 and R13.\u00a0<\/span>
The E6 electrolytic capacitor stabilizes the voltage V2 across the R13 resistor.\u00a0<\/span>

the resistor R12 and the capacitor C8 filter out the high-frequency\u00a0<\/span>
