Claim:
1. A control system for a voltage converter, comprising: a determining unit configured to determine whether the voltage converter is in a first load state or a second load state, the first load state including a light-load state or a disabled state, the second load state including a non-light-load state or an enabled state; a driving circuit in communication with the determining unit and configured to generate a first driving signal when the voltage converter is in the first load state, and to generate a second driving signal when the voltage converter is in the second load state; and a switching circuit implemented as part of the driving circuit and configured such that the driving circuit generates the first driving signal when the voltage converter is in the first load state, and such that the driving circuit generates the second driving signal as a low-noise driving signal when the voltage converter is in the second load state, the switching circuit further configured to form the driving circuit as an inverter such that the first driving signal has a low voltage that is lower than a low voltage of the low-noise driving signal.
