  • Patent number: 5737201
    Abstract: This invention relates to an electronic device for the conversion of electric energy between a voltage source E and a current source J. This device is comprised of cascaded switching cells (CL.sub.k) each having two switches (I.sub.Ak, I.sub.Bk) and comprising capacitors (C.sub.k) associated with the cells for distributing the voltage of the source over the switches, and control logics (LG.sub.k) which condition the exchanges of energy and are synchronized for limiting the voltage supported by each switch to a fraction (V/n) of the supply voltage, for limiting the ripple amplitude of the voltage of the output to the same fraction V/n and for conferring on this ripple voltage a frequency (nF) which is a multiple of the switching frequency (F) of the switches.
