Rectifier and smoothing circuit

Diode bridge DB1 full wave rectifies the 26 VAC from the transformer's secondary
coil. Then smoothing capacitor C40 converts the 26 VAC into approximately
36 VDC. The +24 and +5 VDC voltages are converted from this DC voltage. The
DC voltage is used as the power supply voltage for the switching regulator circuit
at the next stage.
