Abstract
The present application provides a conversion system and a control method, including N power converters and N controllers, and N controllers one-to-one corresponds to the N power converters. In addition to receiving a first side current and a second side voltage of a corresponding power converter, each of the N controllers can also receive a neighboring direct current voltage signal which only reflects second side voltages of other M power converters in the conversion system, and perform voltage control on the corresponding power converter according to the received signal. The present application adopts fully distributed control, and does not need to set up a centralized controller. When parts of controllers fail, the other controllers can continue to work, so the reliability is higher.
