A novel current link distributed MPPT PV system - Overall system prototyping and evaluation

A novel structure for power maximization of the PV (photovoltaic) system under partially condition is presented. By using CSI (Current Source Inverter) instead of VSI (Voltage Source Inverter), the structure of PV system becomes extremely both more simple and reliable than conventional one. It means that MICs (Module Integrated Converters) can be consisted of buck-only converters and electrolytic capacitors can be removed from the inverter. The experimental results confirmed that the total output power captured the sum of each maximum value of PV under shading conditions.
