Sliding mode controller (SMC) based MPPT systems are less effective due to input LC_in tank of boost converter. The LC_in tank at PV node creates the sinusoidal waves of V_pv/I_pv, due to which phase angle (φ) occurs between triangular wave of inductor current (I_L) and sinusoidal V_pv. This creates the adverse effects on SMC operation. In this research work, a series capacitor based boost converter is developed without using the parallel LC_in circuit. Consequently, V_pv/I_pv becomes triangular (pure/semi) and φ factor between V_pv and triangular I_L is minimized. The proposed setup ensures a high frequency operation and better voltage regulation of SMC. Through theoretical, mathematical and experimental studies, the response of PV source with conventional converter and proposed converter have been analyzed. Finally, extensive simulation studies and experimental evidences are presented, which highlights the superior dynamic and steady efficiencies of PV system with proposed topology as opposed to conventional converter and other recently developed MPPT systems.

通过使用简单 SMC 稳压器的改进型升压转换器实现光伏 (PV) 阵列的高效 MPP 跟踪

由于升压转换器槽中的输入LC _，基于滑模控制器 (SMC) 的 MPPT 系统效率较低。PV 节点槽中的LC_产生V _pv / I _pv的正弦波，因此在电感电流 ( I _L ) 的三角波和正弦V _pv之间出现相位角 ( φ ) 。这会对 SMC 操作产生不利影响。在这项研究工作中，开发了一种基于串联电容器的升压转换器，而无需_在电路中使用并联LC 。因此，V _pv / I _pv变为三角形（纯/半），并且V _pv和三角形I _L之间的φ因子最小化。建议的设置确保了 SMC 的高频操作和更好的电压调节。通过理论、数学和实验研究，对光伏源与传统转换器和提出的转换器的响应进行了分析。最后，提出了广泛的模拟研究和实验证据，强调了与传统转换器和其他最近开发的 MPPT 系统相比，具有所提出拓扑的光伏系统具有优越的动态和稳定效率。
