13-1-2 Circuit description [FLY-Back RCC(Ringing Choke Converter)] Control
(a) AC Power Rectification/Smoothing Terminal
1) BD01 : Convert AC power to DC (Wave rectification).
2) C10 : Smooth the voltage converted to DC.
3) C01,C02,C04,C05,C06,BD02 : Noise removal at power input/output.
4) R10 : Rush current limit resistance at the momemt of power cord insertion.
· Without R10, the bridge diode might be damaged as the rush current increases.
(b) SNUBBER Circuit : PTD01 - C13,C12,D10,R11,R12
PTD02 - C18,C19,D15,R20,R21
