Rectifier filter circuit

Rectifier filter circuit

    (2) The 220 V AC voltage filtered by the rectifier filter circuit is rectified by the bridge rectifier stack BD101 and filtered by the filter capacitor Cl01, and then becomes
a DC voltage of about 300 V, which is added to the ① pin of the switching transformer Tl01 to form a switching oscillation circuit. Provides DC bias. Figure 2-38 shows the rectifier filter circuit .
