Description: 为了克服传统两级式光伏并网系统在设备体积、成本和控制复杂度上均存在的不足,提出了一种无直流稳压环节的新型单级式光伏并网系统电路拓扑和适用于此拓扑的电压变化速度受限的最大功率点控制算法(V V S L -M P P T )。使用仿真和实验的方法,对系统的性能进行了验证。实验样机实现连续工作10 h 的稳定运行,输出稳定在系统最大功率点,并于14:0 0:00 左右达到全天峰值。结果表明,在此算法控制下,系统可稳定追踪最大功率点,并对光照突变等恶劣情况,有较强的适应能力。-PV Inverter with Improved MPPT

Description: 传统的燃料能源正在一天天减少，对环境造成的危害日益突出，同时全球还有20亿人得不到正常的能源供应。这个时候，全世界都把目光投向了可再生能源，希望可再生能源能够改变人类的能源结构，维持长远的可持续发展。太阳能以其独有的优势而成为人们重视的焦点，越来越多的国家开始实行“阳光计划”，开发太阳能资源，寻求经济发展的新动力。因此，研究并网逆变器的设计有着广阔的前景和意义。限制光伏系统的主要因素有两点：⑴初期投资比较大；⑵太阳能光伏电池的转换效率低。目前我们通常使用的光伏电池效率在15 左右，即使世界上最先进技术的光伏电池在特殊的实验条件下也只能达到40 ，因此光伏电池最大功率跟踪就变得十分重要，所以长期以来都是学术界研究的热点。-PV Inverter and Battery Charger with MPPT

Description: 《Z源逆变器光伏并网系统模型及电路参数设计》
摘要：建立了Z 源逆变器光伏并网系统的小信号模型，定量分析了光伏模块输出电压动态性能与主电路各参数间的
关系。光伏模块输出电压的最大功率点跟踪（MPPT）控制与系统采样平均周期关系密切，而采样平均周期又受主电路
无源元件参数大小的影响。定量分析小信号模型建立了各部分之间的传递函数，这对选择MPPT 控制采样平均周期
和主电路参数优化设计起到了关键性指导作用。实验证明了理论分析的正确性和该模型的实用性。

Description: 由于太阳能电池受到光强以及环境等外界因素的影响，其输出功率是变化的，光强发出的电就多，带MPPT最大功率跟踪的逆变器就是为了充分的利用太阳能电池，使之运行在最大功率点。也就是说在太阳辐射不变的情况下，有MPPT后的输出功率会比有MPPT前的要高，这就是MPPT的作用所在。(Because solar cells are affected by external factors such as light intensity and environment, their output power is varied. Light intensity emits much electricity. The inverter with MPPT maximum power tracking is designed to make full use of solar cells to operate at the maximum power point. That is to say that in the case of constant solar radiation, the output power after MPPT will be higher than that before MPPT, which is the role of MPPT.)
