Special Issue Information

Dear Colleagues,

Solar photovoltaic technology is the key to achieving carbon neutrality. This requires further innovations in modules, power converters, and control technologies. Nonetheless, over time, PV modules can experience degradation and aging, leading to reduced energy production. Therefore, it is essential to study the effects of aging on PV modules and inverters, as well as the operational conditions of the entire system, through experimental and numerical analysis in order to ensure their long-term performance and reliability, which can help to develop more robust and efficient inverters. This will also help in monitoring the status of the entire system to enable secure and reliable power supply from PV modules. Furthermore, the performance of modules, inverters, and other connected systems is co-related. A top-down view of the entire system may benefit system-level optimization and control.

In this context, this Special Issue on the experimental and numerical analysis of photovoltaic inverters will collect the latest research on PV technologies, in particular power converters. The topics of interest include, but are not limited to:

  • The modeling of solar PV modules (e.g., c-Si and other emerging technologies);
  • The modeling and control of PV inverters;
  • Advanced PV cell technologies;
  • Novel power converters design for PV applications;
  • Data acquisition and analysis in PV systems;
  • The condition monitoring of PV modules and inverters;
  • Experimental verifications with big data;
  • Artificial intelligence in PV systems;
  • The control and testing of PV systems (standalone and grid-connected).

Nowadays, transformer-less photovoltaic (PV) multi-level inverters (MLIs) are commonly employed in both industrial and residential settings. This structure has attracted increased attention due to its unique advantages, such as higher efficiency, lower cost and size, better waveform quality, and inherent fault tolerance. However, due to the removal of the transformer, the common mode voltage (CMV) becomes one of the crucial issues in transformer-less PV MLIs. The high-frequency variation in CMV results in a leakage current that deteriorates the line current quality, increases the PV power system losses, leads to severe electromagnetic emissions (EMI), reduces the PV array lifespan, and causes personal safety problems. In this regard, this paper presents a review of the existing and recent research on modulation techniques based on space vector pulse width modulation (SVPWMs) that overcome this issue in transformer-less three-level NPC-MLIs (3L-NPC-MLIs). The reduced CMV-SVPWM (RCMV-SVPWM) can be mainly categorized as an RCMV-SVPWM based on the vector type, based on virtual vectors, and based on the two-level SVPWM (2L-SVPWM). Their features and their limitations in terms of several main criteria are discussed. In the final section of this paper, some challenges and future trends for this research area are projected.
