研究目的
To enhance the effectiveness and decrease the cost of a Photovoltaic (PV) system by utilizing transformer less PV inverters, and to address issues like effectiveness degradation and safety issues related to the galvanic association between the system and the PV generator.
研究成果
The importance of PV based power generation system with development of novel inverter structures are presented in this study. It’s concluded that a typical transformerless PV system diminishes the weight, size, and cost and installation complication of the complete PV system. A detailed investigation of parasitic capacitance of PV arrays and leakage current is required in future.
研究不足
The study highlights the potential for DC currents to be injected into the AC current in transformer-less PV configurations, which can saturate magnetic components in the supply transformer, leading to overheating and eventual unit failure. It also notes the need for detailed investigation of parasitic capacitance of PV arrays and leakage current.
