<p>The invention relates to a charge transfer module (10) between two dipoles (E1, E2) with a common pin (N), said module being of the tripole type, with a first (A), a second (B) and a third (C) compensation electrode, connected to corresponding pins (P1, P2, N) on the dipoles and comprising a compensation stage, connected to said compensation electrodes, with a high breaker (ST) and a low breaker (SB) in series between the first electrode (A) and the second electrode (B) and an inductance (L), connected between the third electrode (C) joined to the common pin (N) for the dipoles and the connection node (11) between said breakers. Said breakers are each controlled by a control circuit (PWM), providing a breaker switching signal, the cyclic relation of which is fixed by the difference between a measure of the mean current in said inductance and a current set-point (Icons), proportional to the difference in voltage between the dipoles. The above is of application to the equilibration of dipoles in a battery of rechargeable cells, particularly lithium ion or supercapacitance type cells.</p> |
