Abstract
- In this paper, a novel control scheme of the bidirectional isolated dual-active-bridge (DAB) dc–dc converters is proposed to regulate the output voltage and current, based on a sliding mode (SM) control. At first, a mathematical model of the DAB converter is expressed in a state-space form. Then, the output voltage and current controllers of the DAB converter are designed with the double-integral SM control theory, which is robust to the model uncertainty and disturbance. The proposed control method provides not only the zero steady-state error without any chattering but also the fast transient response for load variations and reference changes. The validity of the proposed control algorithm has been verified by simulation and experimental results for a 1.5-kW DAB converter. [ABSTRACT FROM AUTHOR]
