摘要：随着焊接设备、太阳能和风能在生产和生活中获得了越来越广泛的应用，其关键技术（逆变技术）也得到广泛的应用，因此逆变技术在新型能源的的开发利用和焊接设备应用领域有着至关重要的地位；新型的逆变电路和先进的控制技术渗透到逆变电源系统中，使得逆变电源向高频化、低损耗和低谐波畸变率等方向发展，构成了现代逆变电源的三个关键性指标；本文系统地论述了DC-AC逆变电源技术中传统的和新型的电路拓扑，并指明了它们各自的优点，同时也详尽的论述了典型逆变电源系统结构，表明高频环节逆变技术替代低频环节逆变技术是发展的必然趋势。
关键词：逆变器；高频链；拓扑；PWM控制
Abstract: With more and more widespread application of welding equipment, the solar energy and the wind energy in the industry and the lives, its key technologies(inversion technologv) also obtained the widespread application, therefore the inversion technology had the very important status in the new enerrgyand welding equipments development and the application domain. New type of inverter circuits and advanced control technology was through in the inverter power supply system, made the inverter power supply to the high frequency and low loss and low THD, which constitute the development direction of modern inverter power supplys the three key index. The paper systematically elaborated commonly the inverter technology and new type of inverter circuits, and indicated their good and bad points, simultaneously also elaborated the typical inverter system structure, pointed out that the high frequency link inversion technology substituting low frequency link inversion technology is the development trend inevitable.
Key words: inverter; high-frequency link; topology; PWM Contro
