Abstract
It is analyzed detailed the mechanism of common mode current for the transformer-less photovoltaic inverter system. Different control methods are used to analyze the common mode current of single-phase transformer-less full-bridge topology, and some new topologies are also analyzed and simulated. Finally, a new high-efficiency transformer-less photovoltaic generation system which is based on single-phase hybrid clamped three-level inverter is in further research.
