具有虚拟磁导率的增强励磁阻抗无芯变压器

The main difference between coreless transformer (CLT) and conventional ferrite-core transformer is the magnitude of the magnetizing impedance. This article proposes a CLT with virtual magnetic permeability (CLTVMP). The CLT is based on a novel overall-resonance principle of a series of intermediate coils to maximize the magnetizing impedance, which is different from the existing multicoil resonan...
