The photovoltaic standard stipulates that for the detection of photovoltaic leakage current, Type B, that is, a current sensor capable of measuring both AC and DC leakage currents, must be

At high leakage currents, it is not always possible to accurately calculate the residual current. The resulting calculation errors can lead to an undesired shutdown of the inverter.

In this sense, a new single-phase grid-connected transformerless inverter topology was proposed using modulation switching techniques to keep the leakage current at acceptable standard
