Input Filter Circuit
AC line voltage travels to the rectifying circuit through the line filter. The line filter eliminates RFI noise which may otherwise
pass to the AC line from the power supply unit. It also protects the power supply unit from transient noise which may pass into
the unit from the AC line.
Rectifying and Smoothing Circuit
As soon as power is applied to the Power Supply Unit, AC line voltage is rectified by C105 and is smoothed by capacitor C107.
The protection circuit at the time of start-up is controlled by an IC (IC101) and resistors R103 and R110.
Inrush Current Protection Circuit
When the capacitor C105 is not charged by the AC input, an inrush current, or current surge, appears at the input side. Power
thermistor TH101 limits the inrush current.
Converter Circuit
A hybrid IC (IC101), in combination with transformer T1, form a switching power supply circuit using the RCC (Ringing Choke
Converter) system.
