Ph.D. Xu Jun, Vice President of Sungrow Research Center, highlighted 10 Major Technological Trends at Ph.D. Talk:

The Application of New Semiconductor DevicesTo achieve net-zero carbon emissions, advancements in energy generation, transmission, and conversion efficiency are crucial. According to Diamfab, diamond has the potential to become the ultimate WBG semiconductor material for high-power electronics. Diamond possesses ideal characteristics for high-voltage operation, high-temperature applications, and high-frequency switching, with a critical electric field 30 times higher than Si and 3 times higher than SiC.
The Extended Utilization of Solid-State Transformer (SST) Technology and Medium-Voltage Photovoltaic (PV) InvertersThe medium-voltage PV power generation system based on SST technology offers a higher power density compared to traditional solutions, with an overall improvement in conversion efficiency. In the future, SST technology may find applications in MW-level charging stations, HVDC power supply systems for data centers, energy routers, and more. Notably, Sungrow developed the world’s first 35kV SST-based PV inverter in 2022.
Further Enhancement of Direct Current (DC) Voltage Level in PV SystemsThe increase of DC voltage in PV systems not only increases power density and efficiency but also reduces infrastructure and maintenance costs. Notably, Sungrow achieved a groundbreaking milestone by becoming the world’s first company to introduce the 2000V solar-plus-storage high-voltage system and successfully integrating it into the grid in Yulin, Shaanxi.
Improving the Overall Lifecycle Efficiency of PV Power Plants through Digitization and AISungrow has introduced the concept of DEPCO (Development, Engineering, Procurement, Construction, Operation), bringing about comprehensive digitization to renewable energy power plants. The company has developed cutting-edge software solutions, namely iSolarTool for optimizing the design of large-scale PV power plants, and iSolarBP for commercial and industrial PV assessment and design. By leveraging AI intelligence, these innovative tools enable end-to-end system optimization, effectively boosting the efficiency and profitability of renewable energy development. Currently, these solutions are in the industry trial phase.
“PE Agent,” a Power Electronic Designer Based on Large Language Model (LLM)During the energy transition, AI intelligence will play an increasingly significant role. PE Agent  can facilitate seamless communication between AI and AI, as well as between AI and humans, enabling intelligent management of the entire process of power electronics design and achieving “self-learning” and “self-evolution.”
High Voltage Direct Current (HVDC) TechnologyHVDC systems provide faster active power flow control compared to the more established CSC-HVDC technology. Additionally, they offer flexible and enhanced reactive power controllability at both converter terminals.
Source-Grid-Load-Storage Integration: Driving the Rapid Development of Energy Bases and Future Urban ConstructionThe construction strategy for the source-grid-load-storage operation mode in renewable energy integration can leverage multiple energy sources, enhance grid capacity for renewable energy integration and economic efficiency of active distribution grid operations.
Grid-Forming (GFM) TechnologyGFM technology provide rapid, accurate, and standardized dynamic responses to grid faults and disturbances. It offers strong support for the stable operation of new power systems in various application scenarios.
Virtual Power Plants (VVPs)VVPs are networks comprising small-scale energy-producing or storage devices, such as solar panels and batteries, that are aggregated to serve the electricity grid. With the consent of their owners, the energy generated by these devices can be accessed by utilities during periods of high demand or saved for future use.
Green HydrogenThe off-grid solar-hydrogen solution, IGBT-based hydrogen production rectifier power supply, and the integration of hydrogen for complete energy self-sufficiency in residential buildings with PV and battery storage systems can further enhance energy efficiency.

Spark Education (“Spark” or “the Company”), a global leader in providing interactive small group classes for students from Pre-K through elementary school, today announced that it received the “Remote Learning Innovation Award” in the 6th annual EdTech Breakthrough Awards program conducted by EdTech Breakthrough, a leading market intelligence organization that recognizes the top companies and solutions in the global educational technology market.
As a supplementary and enrichment learning provider, Spark Education’s purpose-built platform allows students to take classes from anywhere with an internet connection. With real-time interaction between students and teachers, studio-quality animations, and gamified exercises, Spark Math uses research-proven pedagogy based on Singapore Math and is aligned with the Common Core State Standards. The program reimagines math learning with an online small group format, providing real-time teaching, interactive courseware, and personalization through a proprietary dual-interface classroom platform.
“We know we’re on the right track with our students excelling both in Math and beyond as they develop presentation and communication skills. Many of our students have also been recognized in international math competitions,” said Tina Chen, Vice President at Spark Education Group. “We are pleased to accept this award from EdTech Breakthrough in recognition of our efforts in continuously innovating to provide the best learning experience for students that is efficient and effective, while nurturing a love for learning.”
The mission of the EdTech Breakthrough Awards is to honor excellence and recognize the innovation, hard work and success in a range of educational technology categories, including Student Engagement, School Administration, Adaptive Learning, STEM Education, Remote Learning, Career Preparation and many more. This year’s program attracted thousands of nominations from over 17 different countries throughout the world.
“Spark Education combines technology with proven pedagogy and child psychology to make learning fun, efficient, and effective. Though remote learning has become the norm in many situations, value should still be placed on the personal touch of passionate teachers and the social-emotional benefits of peer learning,” said Steve Johansson, managing director, EdTech Breakthrough. “With Spark, students receive the right level of challenges and coaching to progress at their own pace while also benefiting from peer learning. Spark deserves our ‘Remote Learning Innovation Award’ for its contributions to education through technology, and empowering students to achieve their full potential.”
Spark’s flagship Spark Math program utilizes proprietary interactive courseware and a curriculum that emphasizes the Concrete-Pictorial-Abstract (CPA) approach.
