Abstract
A voltage adjustment system includes a power supply for providing an initial voltage signal, a plurality of buck converters for receiving the initial voltage signal and generating one adjustable output voltage signal respectively, a microcontroller for determining one adjustable output voltage signal to output and determining whether a variable voltage signal generated by a buck converter that outputs the adjustable output voltage signal is positive or negative, a display unit for displaying value of the adjustable output voltage signal that is outputted, a plurality of voltage control units corresponding to the plurality of buck converters, and a voltage variation adjustment circuit including two buttons. The variable voltage signal is added to the adjustable output voltage signal generated by the same buck converter. Selection of the two buttons causes the microcontroller to adjust absolute value of the variable voltage signal generated by the buck converter through the corresponding voltage control unit.
