Abstract
The invention relates to a DC to DC voltage converter including a charge pump capacitor (C) installed parallel to a means () for controlling switches (T, T), arranged to maintain a predefined voltage range on the terminals of the means () for controlling the upper switch (T). The control means () are arranged so as to close the lower switch (T) in order to impose zero electric potential on the central terminal of the star (O) when the upper switch (T) is open, in order to force the charging of the charge pump capacitor (C).
