Transient Response Analysis of Long Primary Loop used on SCMaglev's DWPT System

Abstract

This paper describes the verification of the transient response occurs on the primary loop used on DWPT system for the SCMaglev. The primary loop has long length, order of several kilometers, and high working frequency, near 10kHz. Therefore, the primary loop has both lumped and distributed circuit characteristics. We propose a simplified method to derive approximate transfer function, represents the lumped and distributed characteristics in desired frequency band. The frequency and transient response characteristics calculated by the transfer function are close to the results obtained from field tests.
