Beschreibung
Zusammenfassung:	The invention discloses a single-inductor three-output switch converter current ripple control system and method, and belongs to the technical field of switch converters. Comprising a converter TD and control devices corresponding to switch tubes S1, S2 and S3, and the converter TD is electrically connected with the control devices corresponding to the switch tubes S1, S2 and S3; the control device comprises an inductive current ripple controller CTR1, an output current ripple controller CTR2 and an output current ripple controller CTR3, and the inductive current ripple controller CTR1, the output current ripple controller CTR2 and the output current ripple controller CTR3 are electrically connected with one another. The invention provides a current ripple control system and method for a single-inductor three-output switch converter, which enable the single-inductor three-output switch converter to have better load transient performance and smaller output cross influence, and are suitable for various topologi
