Abstract
PURPOSE: To suppress load fluctuation to obtain a stable output by separating a load part having the same magnitude as the load of a DC power source part in a switching circuit which detects that the load is connected to the output end of the DC power source part.
CONSTITUTION: In DC power source part 1, a DC obtained by rectifying AC power source 5 by 6 is subjected to high frequency conversion by blocking oscillation circuit 7 and is boosted and is rectified by rectifying diode d to obtain a DC output. Between output ends of part 1, first load 2 which is always operated is connected, and second load 3 and resistance R1 are connected through switch 4. Further, load part 10 consisting of a resistance of the same mangitude as load 3 is connected through switch circuit 9. Now, when only load 2 is connected, voltages at both ends of resistance R1 are zero, and transistors Tr2 and Tr3 are turned off and on respectively, and load part 10 is connected to power source part 1. When load 3 is connected through switch 4, voltages are generated at both ends of resistance R1, and transistors Tr2 and Tr3 are turned on and off respectively, and load part 10 is separated. As a result, load fluctuation is suppressed, and oscillation of circuit 7 is stabilized.
