2.4.1 PSB/PSE Board
In the PSB/PSE Board of Stylus Photo RX420/RX425/RX430, the simulated
oscillating stimulation flyback converter circuit method is used, and it supplies
+42VDC to the drive line. The application of the output voltage is described below.
AC voltage input from AC inlet first goes through filter circuit that removes high
frequency components and is then converted to DC voltage via the rectifier circuit and
the smoothing circuit. DC voltage is then lead to the switching circuit and FET Q1
preforms the switching operation. By the switching operation of the primary circuit,
+42VDC is generated and stabilized at the secondary circuit.
