基于无功注入器的近单位功率因数无磁芯直流变压器

With the development of lightweight power electronic devices, converters with coreless designs are gradually receiving attention due to their high gravimetric power density (GPD). This article presents a reactive-power-injector-based coreless dc transformer (RPI-CLDCX) with a near-unity power factor. The RPI-CLDCX has three inverters, two of which transfer only active power, while the third one pr...
