Oscillating circuitThe DC voltage of 300v on C847 run across the primary coils,P1 and p2, of the energy saver transformer, and then it is imposed on C pole of the internal switch of IC801 3-pin, in the meantime, it is imposed on B pole of the internal switch of IC802 2-pin by R803, so that the switch pipe is conducting. Therefore, the voltage in P1 and P1 coil is coupled with F2 and F3, and the positive feedback is imposed on the 2- and 4-pin(i.e the B- and E-pin of the internal switch pipe) of IC801 by C806 and R804, which makes the switch pipe saturated. Stabilized circuitThe stabilized circuit is completed in STR50213.
