This paper studies the non-fragile H∞ state observer design problem for a classof uncertain time delay systems by using the Lyapunov stability theory and thelinear matrix inequality technique. Several results which ensure these systems tobe asymptotic stability are obtained. The obtained results are given by the linearmatrix inequality and can be solved easily. Moreover, the gain matrix of theobserver can vary appropriately. Finally, a numerical simulation shows that theprovided results are effectiveness.

“…One method for suppressing CMV is the use of an active CMV filter [6]. However, hardware solutions, including active CMV filters, require additional auxiliary components, such as common-mode transformers or additional switches [7,8]. Consequently, the system volume increases, and the optimal design of the filter becomes complex.…”

In this article, a finite control set-model predictive control (FCS-MPC) with variable sampling time is proposed. A zero-voltage vector appears in the dead time between specific voltage vectors, resulting in an unintentionally large common-mode voltage. Herein, a large common-mode voltage was suppressed, and the load current was controlled using a voltage vector combination that did not cause a zero-voltage vector in dead time. Additionally, to improve the total harmonic distortion (THD) of the load current, the intersection of the predicted current and the command current by all the volage vectors (VVs) in the combination is confirmed. The VV where the intersection occurs is selected as the optimal VV. This optimal VV is applied to the point where the predicted current and the reference current intersect. The applicable range of the sampling time should be selected by considering the calculation time and number of switching. Through the proposed FCS-MPC strategy, not only can the common-mode voltage be limited to within ±Vdc/6, but an improved THD can also be obtained compared to the existing method using fixed sampling. The proposed method was verified through PSIM simulation and experimental results.

“…In the literature review, many topologies of the transformerless inverter have been proposed to reduce the earth leakage current [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. A simple topology that incorporates 4-arms instead of 3-arms was introduced and tested with some modulation schemes [14,15].…”

“…However, the reduction in the earth's leakage current was limited. A more recent topology named H8 was introduced [21][22][23][24][25][26]. It consists of the traditional 3-arm transformerless inverter connected to the DC bus via two series power transistors.…”

Performance Improvement of H8 Transformerless Grid-Tied Inverter Using Model Predictive Control Considering a Weak Grid

et al. 2022

There is increasing utilization of photovoltaic (PV) grid-connected systems in modern power networks. Currently, PV grid-connected systems utilize transformerless inverters that have the advantages of being low cost, low weight, a small size, and highly efficient. Unfortunately, these inverters have an earth leakage current problem due to the absence of galvanic isolation. This phenomenon represents safety and electrical problems for those systems. Recently, the H8 transformerless inverter was introduced to eliminate the earth leakage current. The present study proposes improving the performance of an H8 transformerless inverter using model predictive control (MPC). The inverter was supplied by PV energy and attached to the grid through an LCL filter. During system modeling, the grid weakness was identified. The discrete model of the overall system, including the PV panel, the boost converter, the H8 transformerless inverter, and the controllers, was derived. Then, the introduced H8 transformerless inverter system was simulated and analyzed by the Matlab/Simulink program. The proposed system response using MPC was tested under step disturbances in the PV insolation level. Moreover, the effect of the weak and strong grid operations was considered. The simulation results indicate that the MPC controller has better performance and high-quality injected power. Despite the excellent performance of the strong grid, the nearly weak grid performance is acceptable. Moreover, the Hardware-in-the-Loop (HIL) of the proposed system was implemented using the DSP target LaunchPadXLTMS320F28379D kit to validate the simulation results. Finally, the system performance under the parameter variations showed good robustness.
