Analysis of Leakage Current Detection in Photovoltaic Inverters Based on Current Sampling
Leakage current suppression is one of the key issues that non isolated photovoltaic systems need to address.To reduce the impact of leakage current on the power grid system,this article analyzes the mechanism of leakage current generation in photovoltaic inverters,summarizes current sampling based leakage current detection methods for photovoltaic inverters,including direct detection and indirect detection methods,and explores leakage current suppression strategies from the perspective of improving the topology structure of photovoltaic inverters.
