Solar systems are promising solutions for addressing climate change and long-term energy security issues,**especially in areas experiencing variable weather conditions. The performance of photovoltaic (PV) energy**systems can be challenged when individual modules of a PV array receive unequal amounts of solar irradiance.**Such conditions lead to uncertain multiple local maximum power points (MPPs) on their electrical**characteristics. It remains a challenge of global optimization to ensure that PV systems operate at their global**MPP rather than at local ones. Therefore, research is needed to reduce energy losses of PV systems under**non-uniform irradiation patterns.**Solantro Semiconductor Corp. is a leader in developing chipsets and reference designs for module-integrated**electronics used in distributed and scalable renewable power systems. In order to increase the PV inverter**performance, Solantro needs to incorporate an advanced controller into its DC-DC power optimizers to operate**at the global MPP. This collaborative university-industry proposal aims to develop an advanced Maximum**Power Point tracking (MPPT) technique to find the global MPP that will increase PV inverters efficiency. The**expected results have the potential to improve the design and manufacturing of advanced PV inverters based on**a new real-time MPPT controller. The platform is targeted to be very cost-effective, highly reliable and readily**adaptable to a variety of PV inverters.

太阳能系统是解决气候变化和长期能源安全问题的有前途的解决方案，**特别是在气候条件多变的地区。当光伏阵列的各个模块接收到不等量的太阳辐照度时，光伏 (PV) 能源**系统的性能可能会受到挑战。**这种情况会导致其电气**特性出现不确定的多个局部最大功率点 (MPP)。确保光伏系统在全球** MPP 而不是本地运行仍然是全球优化的一个挑战。因此，需要进行研究以减少光伏系统在**不均匀照射模式下的能量损失。**Solantro Semiconductor Corp. 是开发用于分布式和可扩展可再生能源的模块集成**电子芯片组和参考设计的领导者系统。为了提高光伏逆变器**性能，Solantro 需要将先进的控制器纳入其 DC-DC 功率优化器中，以便在全局 MPP 下运行**。这项大学-行业合作提案旨在开发先进的最大**功率点跟踪 (MPPT) 技术，以找到可提高光伏逆变器效率的全球 MPP。 **预期结果有可能改进基于**新型实时 MPPT 控制器的先进光伏逆变器的设计和制造。该平台的目标是非常经济高效、高度可靠并且易于**适应各种光伏逆变器。
