2.3.2.3 Rectifier and Smoothing Circuit
The 26
VAC
from the secondary coil of the transformer are full-wave rectified by diode bridge DB 1,
and converted to approximately 36
VDC by smoothing capacitor C 1. The +24 VDC and + 5
VDC
voltages are converted from this DC voltage, which is used as the power supply voltage for the switching
regulator
IC
at the next stage.
