Beschreibung
Zusammenfassung:	A control method and device of a voltage converter and a voltage control system are provided. In some embodiments, the control device includes a first control module configured to obtain a current reference value according to an output voltage of a voltage converter and a given voltage value; a current modulation module configured to reduce the current reference value when an output current of a voltage converter is greater than a first current threshold; and a second control module configured to control the output current of a voltage converter according to the reduced current reference value and an output current.
