Performance Analysis of Snubber Circuit Integration in Transformerless Inverters
IOP Conference Series: Earth and Environmental ScienceAbstract Transformerless inverters are widely employed in photovoltaic (PV) systems due to their reduced cost, weight, and improved efficiency. However, the absence of galvanic isolation introduces leakage current, primarily caused by common mode voltage fluctuations.
