- This so-called "upstream reservoir” of energy reservoir is for example a capacitive reservoir supplied by the voltage regulator stage 21.
- the DC-DC converter main 22 and the starter module 24 are for example transistor stages whose structure, known elsewhere, is not detailed here.
- the second DC-DC converter stage 23, secondary converter is a DC-DC multitension converter of conventional structure also known. However, in the context of the invention, its commissioning is, as for the first converter stage 22, controlled by a control input on which it is necessary to apply a signal to turn on the converter.
- This control signal is produced by the starting module 25 which activates this signal when the voltage V M is established and stable enough to withstand the current draw at the start of secondary DC-DC converters .
- the first converter stage 22 also comprises an energy reservoir (not shown in the figure) dimensioned appropriately to provide in time the energy required to ensure a startup without transient instability of the DC converters.
- Secondary-DC secondary second stage 23 This energy reservoir called “downstream reservoir” is for example a capacitive reservoir powered by the first DC-DC converter stage 22.

- the secondary conversion stage 23 may be followed by a regulation stage (linear regulation) intended to create other usual voltages (2.5 V, 1, 2 V , ... etc.).
- the operation of this module in startup mode includes, as illustrated Figure 3, three main phases.
- the first phase (phase 1) consists in establishing a regulated shunt voltage V REG of low value, typically less than 3 V, or shunt voltage, from the direct current flowing on the power supply line. 14 of the antenna.
- the duration of this first phase is a function of time Tr-i necessary to obtain a voltage V REG perfectly established and stable, and the time Ti necessary to the load of a capacity upstream energy reservoir sufficient to ensure the sequential start of the first DC-DC conversion stage 22 without any instability (ie without oscillation of the main DC-DC converter).
- the second phase (phase 2) consists in starting the main DC-DC converter 22 after a delay (Tempo 1) sufficient (ie at least equal to Tr-i + Ti) to allow the complete progress of the first phase (ie stabilization of the low voltage shunt and upstream energy tank load).
- This second phase is a function of the time Tr 2 necessary to obtain a stabilized voltage V M at the output of the main DC-DC conversion stage 22, and the time T 2 necessary for the load of a downstream energy reservoir sufficient to ensure the sequential start of converters forming the second DC-DC conversion stage 23, without any instability (ie without oscillation of secondary DC-DC converters).
- the DC-DC converter stage main 22 provides a stable voltage rise V RE G (2.2 Vdc) voltage V M (5 Vdc). It thus makes it possible to accommodate the low shunt voltage, V RE G (2.2 Vdc), delivered by the regulation stage 21.
- the energy stored by the downstream capacitive energy reservoir provides the necessary energy to absorb the starting currents (Inrush currents) secondary DC-DC converters without requiring the delivery of an output current excessive on the part of the main DC-DC conversion stage, current that would require to oversize this stage, simply to meet the demand of secondary DC-DC converters at startup.
- This phase starts after a sufficient time delay Tempo 2 (ie at least equal to Tr 2 + T 2 ) to allow the complete development of the second phase.
- the start of the secondary DC-DC converters is sequenced and finely controlled (rise time Tr n of the secondary power supplies and delays Tempo n), to accommodate on the one hand the energy available in output of the main DC-DC conversion stage 22 and secondly to ensure, as has been said above, the respect of the requirements of programmable circuits and memories.
- V REG voltage regulator delivers a shunt voltage, V REG , low level and the delivery of a higher shunt voltage (6.8 V instead of 2.2 V for example) would achieve a comparable volume tank energy upstream with a much larger capacity, able to provide a much higher energy at startup and, therefore, to relax the start sequencing constraints of the main DC-DC.
- the delivery of a higher shunt voltage could even under certain conditions allow operation without energy reservoir.
