CIRCUIT OPERATIONAL DESCRIPTION
5) Costant-voltage Circuit
This circuit maintains constant voltage. When voltage is lower or higher than reference voltage(2.5V) of
IC801 pin1, this circuit compensates for a loss. Base voltage of Switching TR is controlled and final
voltage is regulated by increasing or decreasing Internal Diode Current of IC801.

6) Secondary rectification circuit
This circuit generates DC voltage needed to each terminal. It is rectified half-wave by D821, passes
through Electrolytic Condenser C825 and generates the rectified DC voltage. DC voltage passes
through L821, C822 and is removed of Ripple and Noise. The other terminal operation is same like
this.
