Method for controlling a serial electrical distribution system and associated serial power distribution system

An electrical distribution system, comprising:

• a power supply device, configured to deliver a first current, which is a single-phase AC current, associated with a first voltage, which is a single-phase AC voltage between 10 kV and 35 kV,
• a plurality of electrical loads, and
• a plurality of conversion modules, the conversion modules being respectively associated with the electrical loads,
• each conversion module comprising input terminals and output terminals,
• the input terminals of all conversion modules being connected in series to each other and to the power supply device, the first current thus flowing between the input terminals of all conversion modules, the first voltage being thus applied to all conversion modules, and
• the output terminals of each conversion module being connected to the electrical load associated with the conversion module,
• wherein each conversion module comprises:
• a group of transistors, connected between the input terminals of the conversion module,
• at least one capacitive element, connected to the group of transistors,
• a converter, connected to the group of transistors and to the output terminals of the conversion module, and
• an electronic control unit, configured to control each transistor of the group of transistors,
• wherein the group of transistors of each conversion module is configured to deliver to the converter of the conversion module a DC voltage and a DC current, from the AC voltage at the input terminals of the conversion module and the AC current flowing between the input terminals of the conversion module,
• wherein the converter of each conversion module is configured to deliver to the associated electrical load a constant DC voltage between 48 V and 400 V and a DC current, from the DC voltage and DC current delivered by the group of transistors of the conversion module,
• and wherein the electronic control unit of each conversion module is configured to regulate an amplitude of the AC voltage at the input terminals of the conversion module and a phase shift between the AC voltage at the input terminals of the conversion module and the AC current flowing between the input terminals of the conversion module, by controlling the group of transistors of the conversion module and using the at least one capacitive element of the conversion module.
