<p>PURPOSE:To limit a current that flows through an anode terminal by connecting a resistor in a stage before a multiplier inside a flyback transformer. CONSTITUTION:The part surrounded by the broken line (capacitors C1-3, diodes D1-3, multiplier) forms a voltage doubler rectifier circuit, and generates a DC voltage. As shown in the figure, by connecting the resistor R in the stage before the internal multiplier, a current flowing through the anode terminal can be limited. The valve of resistance of the resistor to be connected varies according to the value of the current to be limited. As a result, no variation occurs in view of the characteristic of the flyback transformer in achieving said limitation of the current.</p> |
