Voltage converter including at least: a boost circuit to convert an input voltage Vin to an output voltage Vout, a setpoint for the output voltage Vout is, by a fixed additional value Vf, larger than the input voltage Vin, and the fixed additional value is independent of the input voltage Vin measurement circuit emits an electrical trigger signal based on a difference between the output voltage Vout and the input voltage Vin, and a trigger circuit adjusts the output voltage Vout depending on the electrical trigger signal.
