This paper proposes a new method to calculate switching angles in selective harmonic elimination technique. It is introduced as a substitute for Newton–Raphson method and similar iteration methods. By utilizing classical control such as the proportional-integral (PI) control, the proposed method can perform a real-time calculation for multilevel inverter’s (MLI) switching angles over a wide range...
Differential mode Three-phase Micro inverter DTMI has many features in low voltage application such as module integrated PV architectures. It has the ability to increase the PV module voltage using single stage with low components count. Differential inverter is implemented using three DC-DC converters with their input terminals connected in parallel and their outputs terminals connected differentially...
This paper proposes a new design and implementation of a single stage three-phase multi-level inverter (MLI). The suggested inverter is modular type and can be generalized by connecting the basic modular cells in series configuration. In addition, it can be operated with symmetrical/asymmetrical Dc-voltage sources. The proposed MLI is successfully modulated using sinusoidal pulse width modulation...
Mismatching effects are major drawbacks existing in today's photovoltaic (PV) solar systems. To improve power system stability and energy conversion efficiency, distributed maximum power point tracking (DMPPT) techniques are developed. In this paper, single-stage DMPPT power management DC-AC inverter architecture (SS-AC-DMPPT) is presented and verified by Matlab®/Simulink® simulation model results...
