چکیده
This article presents a control strategy for dual-input neutral-point-clamped (NPC) inverter-based grid-connected photovoltaic (PV) system to asymmetrically the PV arrays without incorporating any additional external circuit. is achieved by employing an analytically developed linearization block, which helps in generating required neutral point (NP) current counter difference currents. The analysis also provides maximum NP compensation limits of NPC inverter. If reference less than limit, both operate at their power points. However, if exceeds one operates its point, while output other array reduced satisfy limit. Experimental tests are conducted on laboratory prototype validate performance proposed strategy.
