Claim Text:
1. A voltage adjustment system, comprising: an adjust module comprising a voltage converting unit which comprises a buck converter and an inductor; the buck converter comprising a current feedback terminal and a voltage feedback terminal; a control module comprising a first resistor, a second resistor and a variable resistance unit; and a load module electrically connected to the current feedback terminal via the inductor; wherein a connecting point between the inductor and the load module is grounded via the first resistor and the second resistor in series; the voltage feedback terminal is electrically connected to a connecting point between the first resistor and the second resistor; the connecting point between the first resistor and the second resistor is grounded via the variable resistance unit; the variable resistance unit comprises a thermal resistor being located adjacent to the inductor; a resistance of the thermal resistor changes when a temperature of the inductor changes; and an equivalent resistance of the variable resistance unit changes to adjust a voltage received by the load module; wherein the variable resistance unit comprises a third resistor, a fourth resistor and a fifth resistor; the connecting point between the first resistor and the second resistor is grounded via the third resistor and the fourth resistor serially; and a connecting point between the third resistor and the fourth resistor is grounded via the fifth resistor.
