Abstract
This paper proposes a fault tolerant differential power processing (DPP) scheme for parallel-connection photovoltaic (PV) modules. The proposed DPP utilizes two switches to achieve voltage balance and power balance under shadow faults. The switches are also connected with an LC resonant tank as a resonant switched capacitor converter (RCSS) to confirm the DPP can operate properly under the open-circuit fault (OCF) and the short-circuit fault (SCF). The circuit is significantly simplified since only two switches are required while the number of submodules can be expanded in each module. A 320-W PV system containing four modules is built and tested with the power improvement of 18.36%.
