As shown in Figure 8-1, 3 rectifiers (or more) are chained in parallel to provide the
current capacity needed. The output voltage of the rectifiers feeds the load and
charges the batteries through the dual LVD.
A dedicated bus that connects all rectifier modules does current sharing.
This is done autonomously and not related to the system controller.
All rectifiers are sharing a voltage control bus (V-CONTROL) by which it is
possible to change the output DC voltage of the system, around the default value of
the modules.
This bus is controlled by the system controller in order to change the output.
