© 2014 IEEE. In grid-tied photovoltaic (PV) power systems, the significant power variation that is caused by solar irradiation intermittency is one challenge for consistent efficiency and power quality. In particular, the system suffers from low system efficiency and poor power quality under low solar irradiation condition. Burst mode operation is a possible solution to the above issues and helps maintain a quality injection of PV energy. However, over/under voltage fault may happen by adopting the conventional burst mode operation. In this paper, a comprehensive control strategy is proposed to achieve high performance of the burst mode operation and prevent the violation of DC-link voltage limits. Simulation and experimental results are presented to support the recommended operations.
