Abstract
A cascade circuit can include: N power conversion units connected in series between two ports of a power supply, where N is a positive integer greater than or equal to 2; a controller connected to one of the N power conversion units, and being configured to send a signal to be transmitted through the connected power conversion unit; where each of the power conversion units is configured to send the signal to be transmitted to a next-stage power conversion unit when the each of the power conversion unit shares a reference voltage with the adjacent next-stage power conversion unit; and where the signal to be transmitted is controlled to be transmitted from a previous-stage power conversion unit to a next-stage power conversion unit in sequence until the signal to be transmitted is received by all of the N power conversion units.
