For safety purposes, many photovoltaic (PV) systems are designed using galvanic isolation and transformers. The main problem in the existing topologies is that transformers are expensive, heavy and large. Another problem is that at conversion stage, the overall frequency is reduced. The efficiency of a PV inverter which is equipped with a transformer is usually between 91 and 94%. To tackle this issue, a transformerless (TL) PV system is proposed which has high efficiency and is lighter and cheaper. Due to stray capacitance, harmful leakage current will flow to the grid and PV array. H5, HERIC, H6 and oH5 are different types of existing TL inverter, and may be used to solve this problem. Each configuration has its drawbacks like shoot-through issues of switches, high conduction losses, metal-oxide-semiconductor field-effect transistor reverse recovery issues, or to avoid shoot-through fault when dead time requirements and grid voltage are nearly zero. The efficiency of the proposed TL inverter presented in this study is compared with other existing configurations. It shows that the proposed inverter efficiency is better than the conventional hard switching inverters. Moreover, to increase reliability, the inverters do not contain any shoot-through issues.
