Application of Power Series Technology in Large Current Transformer Test

阐述功率电力电子电源与电工电源串联技术,采用三相桥式整流技术和单相正弦逆变技术,将三相380V的电源转变成单相可调电压源,为大功率升流器提供电源。采用功率电力电子电源与电工电源串联的技术,实现大功率下供电由三相电源来供电,提供更大的电源容量,提高电源利用率,减小供电线路的电流,而且保证了现场供电的三相基本平衡。

This paper describes the power electronic power supply and electrical power supply series technology,using three-phase bridge rectifier technology and single-phase sinusoidal inverter technology,the three-phase 380 V power supply into a single-phase adjustable voltage source,to provide power for high-power converter.By using the technology of power electronic power supply and electrical power supply in series,the power supply under high power is realized by three-phase power supply,which provides greater power capacity,improves the utilization rate of power supply,reduces the current of power supply line,and ensures the three-phase basic balance of field power supply.
