CIRCUIT DIAGRAM
VE1.0 Series Block Diagram
2) Primary rectification and smoothing circuit
AC voltage passed through AC lnlet is rectified to Brige Rectification Diode D801 and changes to
DC voltage. After that it smooths the Smoothing Condenser C806.
When C806 is charged at first, Resistor R802 intercepts voltage current and protects D801, F801.
Start Resistor R803, R804 supply Control IC VCC terminal with rectified DC voltage.

1. POWER SUPPLY OPERATION
1) AC input and EMI FILTER
AC inlet consists of Line Filter, X-Cap, Y-Cap, Varister. Line Filter(L801, L802), X-Cap(C803,
C804), Y-Cap(C801) belong to EMI Filter section. They decrease noise to get into and out of AC
Line.

Snubber circuit

3) Snubber circuit
Snubber circuit protects speedy voltage rising between Collector and Emitter when Main Switching TR is
turned off. So Collector and Emitter voltage enter into safety operation and noise is decreased. When TR
is turnd off, because high reverse voltage is generated between Collector and Emitter, it is rectified to
D802, smoothed to C807 and consumed to R809. C808 is Speed-Up Capacitor.
4) Switching and Control Drive Circuit
When Base of TR is charged through starting part, TR is turned on. So voltage is added to primary
winding of transformer and genertaed at Base Drive. Because this voltage becomes to Positive Feedback
voltage, TR is turned on again and Primary Winding of Trans is charged with electricity .

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.

Costant-voltage Circuit

6) Secondary rectification circuit
This circuit generates DC voltage needed to each terminal. It is rectified half-wave by D821, passes
through Electrolytic Condenser C821 and generates the rectified DC voltage. DC voltage passes
through L821, C829 and is removed of Ripple and Noise. The other terminal operation is same like
this.

CIRCUIT OPERATIONAL DESCRIPTION
7) Output terminal
When power is turned off at power applied status, High signal (+3.3V) is applied to Q804 Base
terminal and GND is applied to Q803 Base terminal and MVCC(+5V) is applied to Q803 collector
terminal.
When power is turned on, Low signal(0V) is applied to Q804 Base terminal and Q804 is shorted. At
this time, Q803 Base terminal becomes High status and Q803 is activated.
Q803 outputs +5V to Emitter terminal.
