基于在线迭代轨迹优化策略的单级微型逆变器轻载效率提升

Due to the inherent intermittency of solar energy, photovoltaic microinverters (MIs) often operate under prolonged light-load conditions. To improve energy utilization, this article proposes a novel online iterative trajectory optimization strategy for the single-stage series resonant dual-active-bridge (DAB) MI to enhance the light-load efficiency. Through the zero-voltage switching (ZVS) conditi...
