<p>PURPOSE:To automatically and continuously fluctuate an output voltage by providing an output voltage control circuit for controlling a DC power source unit. CONSTITUTION:In case of a voltage fluctuation test, when the upper limit value UV and the lower limit value LV of a voltage are set by an output fluctuation voltage setting device 11, and the upper limit output voltage generation time T1 and the lower limit output voltage generation time T2 are set by an output fluctuation time setting device 12, an output voltage control circuit 13 reads these set values and controls an output voltage of a constant-voltage DC power source unit 1, and the constant-current DC power source unit 1 outputs a voltage corresponding to voltage setting and time setting, as a time chart shown in the figure. In such a way, the output voltage can be fluctuated automatically and repeatedly, and a desired output can be obtained without necessitating an adjustment technique of a high level.</p> |
