Voltage/current or current/voltage conversion system

A voltage-to-current or current-to-voltage conversion system, comprising input terminals and output terminals, and between the input terminals and the output terminals:

• a first set and a second set, each of the first set and the second set comprising at least one switching cell, and wherein:
• the system further comprises a common control device for the first set and the second set,
• each switching cell comprising:
• a first switch, which can be in an on state or in an off state, and comprising a transistor, and
• a second switch, which can be in an on state or an off state, and comprising a transistor and/or a diode,
• so that, for each switching cell, this switching cell oscillates between two states, a first state in which its first switch is on when its second switch is off, and a second state in which its first switch is off when its second switch is on,
• the number of switching cells in the system being even,
• each of the first set and the second set comprises the same number of switching cell(s)
• the at least one switching cell of the first set and the at least one switching cell of the second set being associated in pairs so that each switching cell of the first set is associated with a single switching cell of the second set, and each switching cell of the second set is associated with a single switching cell of the first set,
• the control device being arranged and/or programmed to send to the switches of the switching cells a signal arranged to switch the switches between their on state and their off state at a same switching frequency Fdec for all the switches so that, for each pair of switching cells, the first switch of the switching cell of the first set of the pair is off when the first switch of the switching cell of the second set of the pair is on, and the first switch of the switching cell of the first set of the pair is on when the first switch of the switching cell of the second set of the pair is off.
