Abstract

This paper reports empirical and numerical analyses on the electrical behavior of no-insulation (NI) coil. The spiral and radial current flows of NI coil in the case of the nominal operation and over-current condition are quantitatively identified using numerical analysis. Moreover, the origins of charging/discharging delays and magnetic field saturation are discussed in detail. Experimental results are also compared with the simulations to validate the numerical approach.
