Abstract :
In this paper, a 50kW multi-string photovoltaic power conditioning system (PV PCS) and control schemes are proposed and analyzed. The PV PCS consists of five 10kW three-phase interleaved dc-dc converters and a 50kW centralized inverter with LCL-filter, whose controllers are connected through CAN communication for synchronization and ripple current reduction. Prototype of multi-string PV PCS is implemented and tested for the proposed several control schemes.
