<p>PURPOSE:To improve an output secondary distortion caused by the load capacity of an output part by securing difference between the forward charging time and the reverse charging direction of a capacitor that prescribes an oscillation frequency. CONSTITUTION:Transistors (TR) Q6 and Q7 are driven by the same voltage supplied from a constant voltage source 8. Then the current I1 flowing through the TR Q6 and the current I2 flowing through the TR Q7 have different levels as constant current in response to the ratio between resistances R3 and R4 owing to these two resistance having different resistance values. Thus the duty ratio of the oscillation output having 50% deviation due to the load capacity CL is corrected by 50% in terms of the center level of the oscillation amplitude. Thus, it is possible to reduce an output secondary distortion caused by the capacity CL.</p> |
