Claim:
1. A control device for regulating and balancing currents, for DC/DC converters, between first and second voltage sources, the device comprising: n converters that are connected in parallel to the first voltage source; n inductors that have their outlets connected to the second voltage source via n connections; and n current sensors that are arranged on respective ones of the connections; a single regulator system that has its inputs connected to respective ones of the n current sensors, and its output connected to the n converters, wherein the regulator system comprises: a summing circuit for summing the currents output from the current sensors; a PID block that receives the current output from the summing circuit; a 1/n divider that receives the current output from the summing circuit and that delivers an average current; n comparators for comparing the currents measured by the current sensors with the average current; n proportional gain elements that are arranged at the outputs from the comparators; n summing circuits for summing the outputs from the n proportional gain elements with the output from the PID block; and a PWM block that receives the outputs from the n summing circuits and that delivers n interleaved channels.
