VOLTAGE CONVERTER, POWER SUPPLY AND METHOD OF CONTROLLING VOLTAGE CONVERTER

According to the embodiments of the present disclosure, a voltage converter, a power supply and a method of controlling a voltage converter are provided. The voltage converter includes: a converter module configured to convert an input voltage to an output voltage; a current sharing terminal configured to be connected in parallel with a current sharing terminal of each of at least one other voltage converter; and a control circuit configured to: generate a first voltage signal proportional to an output current of the converter module with an adjustable first proportional coefficient and output the first voltage signal to the current sharing terminal; wherein the first proportional coefficient is selected based on whether the voltage converter is a master voltage converter or a slave voltage converter in a current sharing mode; generate a first current signal proportional to a second voltage signal at the current sharing terminal with a second proportional coefficient, wherein the second voltage signal is a largest voltage signal among the first voltage signal and other voltage signal from each current sharing terminal connected in parallel; subtract the output current of the converter module from the first current signal so as to generate an error current signal; and adjust the output voltage of the converter module based on the error current signal.
