Beschreibung
Zusammenfassung:	The invention discloses a hybrid three-level dual-active bridge expansion phase shift optimization modulation method, which specifically comprises the following steps of: calculating real-time transmission power P0 and a real-time voltage conversion ratio M according to given output voltage and output power requirements, judging a working mode of a hybrid three-level dual-active bridge converter according to given conditions, and performing phase shift optimization modulation on the hybrid three-level dual-active bridge converter according to the working mode of the hybrid three-level dual-active bridge converter. A corresponding optimal solution expression is specifically adopted according to specific working condition judgment; and calculating corresponding optimal DP0, DP1 and DSS so as to drive 10 switch tubes of the hybrid three-level dual-active bridge converter, thereby realizing control of the hybrid three-level dual-active bridge extension phase shift optimization modulation method.
