1. A DC voltage converter system comprising:
at least two dividing modules positioned in parallel;
an error module configured to generate an error signal indicative of an error between an output voltage and a reference voltage;
a storage module configured, for each dividing period, to store the error signal and to transmit the identical stored error signal to all the dividing modules instead of the error signal; and
a synchronization module configured to produce, for each dividing period,
one synchronization signal for each respective one of the dividing modules allowing the respective driving of the respective dividing modules in an interleaved manner, and
a storage signal controlling the storage module to store the error signal, a storage pulse of the storage signal being offset in relation to any pulse of one of the synchronization signals.
