New Auxiliary Vector Synthesis for Expanding Linear Modulation Range With the Ability to Eliminate CMV Spikes in the SVM Three-Phase Inverters

IEEE Access
Some strategies are used to reduce the high output common-mode voltage (CMV) in three-phase inverters with the space-vector modulation (SVM). However, these reduced CMV (RCMV) strategies may still lead to high spikes in some cases.

Harmonic Stability Assessment of Commercially Available Single-Phase Photovoltaic Inverters Considering Operating-Point Dependencies

Solar, 2023
The growth of renewables in the energy sector, e.g., in public low-voltage networks, leads to an increasing share of installed power electronic devices, e.g., inverters for photovoltaic applications. To rely on these devices, suitable analyses have to be

The Effect of Inverter Failures on the Return on Investment of Solar Photovoltaic Systems

IEEE Access, 2017
Return on investment (ROI) analyses of solar photovoltaic (PV) systems used for residential usage have typically shown that at least 10 to 12 years is needed to break even, with this amount varying based on tax credits and reliability.

Performance ratio of photovoltaic installations in France: Comparison between inverters and micro-inverters

, 2021
The efficiency of a photovoltaic installation is determined by its performance ratio (PR). This ratio depends on many parameters including orientation, inclination, shading, losses in cables, and number and performance of panels.
