Abstract

In this paper, the sliding mode controller (SMC) based on reference triangular wave (RTW) is presented to obtain a constant switching frequency and remain the advantages of traditional SMC. The basic frame and operation of the new control strategy is introduced. The analysis and design for new controller scheme of voltage source DC-AC Buck inverter is presented. The system parameters and characteristics are analyzed by an equivalent circuit. The relationship between RTW part and SMC part is researched in this paper. Finally, the proposed method is validated by the experimental results.
