Control system for a voltage converter

A control system for a voltage converter, said control system comprising:

• a first switch, a second switch, a third switch and a fourth switch connected in series,
• said first switch having a first output terminal,
• the common terminal of said first switch and said second switch defining a second output terminals,
• the common terminal of said second switch and said third switch being intended to be connected to an input voltage,
• the common terminal of said third switch and said fourth switch defining a third output terminals,
• said fourth switch having another output terminal intended to be connected to a ground potential,
• said first, second and third output terminals being intended to be connected to a voltage converter of a first type or to a voltage converter of a second type,
• detection means connected to said third output terminal, to generate a detection signal indicating said first type or said second type of voltage converter,
• a circuit intended to generate, from a clock signal and said detection signal, control signals intended to control said first, second, third and fourth switches.
