One of the main drawbacks of transformerless topologies is the presence of a leakage current between the physical earth of the grid and the parasitic capacitances of the photovoltaic module terminals.

One of the main drawbacks of transformerless topologies is the presence of a leakage current between the physical earth of the grid and the parasitic capacitances of the photovoltaic module terminals.

In transformerless inverters, leakage current flows through the parasitic capacitor (between the ground and the PV panel (C PV)), the output inductors (L 1, L 2), and the ground impedance (Z G) as shown in Fig. 2.

During operation the PV modules are connected to the AC grid via the inverter. Thus, depending on the device type, a portion of the alternating voltage amplitude arrives at the PV module.

There are two distinct methods to eliminate the leakage current in the solar PV array system: (i) obstruct the leakage current, (ii) reduce the variation/constant common-mode voltage. The additional diodes/switches are incorporated in the system to obstruct the leakage current by disconnecting the PV array from the grid side network.

In photovoltaic systems, parasitic capacitance is often formed between PV panels and the ground. Because of the switching nature of PV converters, a high-frequency voltage is usually generated over these parasitic capacitances; this, in turn, can result in a common-mode current known as leakage current.
