The temperature value and the predetermined value 42 determine the predetermined voltage value outputted to generate the control signal. When the measured temperature value is greater than the predetermined value 42, the predetermined voltage value of the current output is smaller than the previous output. The predetermined voltage value, when the measured temperature value is less than the predetermined value 42, the predetermined voltage value of the current output is greater than the predetermined voltage value of the previous output. Under such a cycle, the power supply of the present example By comparing the measured temperature value with the predetermined value 42, the conversion voltage is automatically adjusted, thereby affecting the output current and the output voltage, and achieving the same voltage and current as other parallel power supply outputs. The amount of increase or decrease of the predetermined voltage value for each output may be adjusted linearly, down, or quantitatively, and is not limited.
