Abstract
The present application provides a conversion system and a control method, including N power converters and N controllers, where each power converter includes a first side and a second side, the first sides of the N power converters are electrically coupled in series, and currents flowing through the first sides of the N power converters are the same, the N controllers correspond to the N power converters one to one. Each controller contains a common-mode voltage loop and a current loop. The common-mode voltage loop is configured to receive a voltage reference signal and a voltage feedback signal, and output a given signal. The current loop is configured to receive the given signal, a current reference signal, and a first side current of a corresponding power converter, and output a common-mode control signal to modulate a first side voltage of the corresponding power converter.
