Abstract

Nowadays, the development of sustainable transportation has been researched all over the world and Korea Railroad Research Institute (KRRI) is conducting a study in order to apply the sustainable Contactless Inductive Power Supply Technology to the electric railway system. But, inherent large flux leakage has limited the high power transmission because the gap of the Inductive Power Transformer(IPT) is much larger than one of the conventional transformers. In this study, a method to compensate the leakage flux and improve the power transmission by using LLC resonant inverter was proposed, incorporated in a built system, and verified by experimental work.
