摘要
本文介绍了无工频隔离变压器型光伏并网发电逆变器的设计要求,分析了取消隔离变压器所带来的技术经济收益和必须克服的技术难点,并结合自己的设计实践和产品测试情况,介绍了基本实现方法和目前达到的技术指标。
This report documents the development of a transformerless technology for PV inverter.The approach is described and the performance of the new device is demonstrated on both a theoretical basis and results from tests.The results have been demonstrated that this transformerless design is effective for higher efficiency,lower cost and more safety.
