Description

---

This volume outlines the global energy situation and current status of photovoltaic power generation both in and outside of China. From there, it goes on to discuss the basic principles and electrical characteristics of photovoltaic cells, evaluating various major MPPT tracking algorithms and isolated island protection technologies, and analyzing the implementation of digital phase-locked loops (DPLL). It goes on to explore a variety of circuit topologies and common principles of mode current suppression techniques for non-isolated single-phase photovoltaic grid-connected inverters, alongside examinations of partial shadow problems and their suppression methods. It also covers single-phase and three-phase control strategies for PV grid-connected inverters, and the DPWM technology used to improve the efficiency of inverters. Finally, it evaluates various low-voltage, ride-through control methods.

Sun Xiangdong graduated from Xi’an University of Technology in 1998, and continues to teach there. From 2006 to 2008, he undertook postdoctoral research into power generation technology for new energy at the Tokyo Institute of Technology, supported by a scholarship from the Japanese Ministry of Education. He has worked on a project for the National Natural Science Foundation in China, and is in charge of two projects for the Shaanxi Natural Science Fund, as well as two special projects funded by the Provincial Education Department. He presided over two enterprise projects involving 50kW and 10kW grid-connected inverters, and more than ten enterprise projects concerning inverters and resonant switching power supplies.
