Emerging photovoltaic (PV) technologies have enabled the creation of intentionally non-flat PV modules for energy generation. Doing so however has significant implications to the power electronics since these cells are not coplanar by design. Non-uniform insolation from cell-to-cell gives rise to non-uniform current density which limits the ability to series-connect these cells without bypass diode...
A typical photovoltaic (PV) power system is composed of multiple strings of PV arrays with one central inverter or a combination of PV modules with micro-inverters. Per-module DC-DC converter and series connected multilevel inverter topologies are possible candidates. In this paper, the analyses of common mode voltages and currents in the afore-mentioned PV topologies are detailed. The grid integration...
