Input voltage is single 120V. CY101, CY102, CY103, CY104, CY105, CY106 are used high frequency noise of primary between common GND.LX101,LX102,CX101, CX102 is used to filter low frequency noise.

  • Page 86 Fig.6 BD101 is a rectifier in which there are 4 build-in diodes, inverting AC to DC. CP111 is used to smooth the wave from rectifier. FR101, and FR201 is a fuse resistor to protect the following circuit when inrush current is too large. UP101 is a current-mode PWM controller with excellent power-saving operation, the number of external components and drastically simplifies the PFC implementation .It also integrates high safety protection features that make the SSC2012 a driver for robust and compact PFC stages.
  • Page 87 When QL101 & QL102 is turned on, the main current flow will be consumed through DL101, DL102, RL108 RL109, RL110,RL113,RL111 and RL114, This will prevent QL101 & QL102 from being damaged under large current impulse and voltage spike.
