Bifurcation Limits and Non-Idealities Effects in a Three-Phase Dynamic IPT System

Multi-phase dynamic inductive power transfer (DIPT) systems are capable of achieving uniform power transmission with low control complexity and high efficiency. To achieve acceptable power capabilities, D-IPT systems have to work in resonance configurations. In contrast to transformers, and due to t...
