In this paper, we describe a BPSO optimized ntsmc for DC-AC converters, which can generate low THD and fast transients. The importance of ntsmc lies in the limited time of system state convergence and there is no singularity. In addition, ntsmc parameters should be selected for optimal performance. Traditionally, these parameters are determined by repeated experiments, which is very tedious, difficult to implement and time-consuming. Therefore, BPSO is used to optimize ntsmc parameters to produce better transient and steady-state response. Lyapunov method is used to analyze the stability of the improved technology. The finite time reachability of sliding surface, the asymptotic stability of closed-loop system and the finite time convergence of tracking error are proved. Therefore, we believe that the improved technology will contribute to the control design of future AI related systems. The prototype of DC-AC converter is simulated and tested with DSP to verify the applicability of the improved technology.<br>
