A modified cascaded multilevel converter topology for high power bidirectional inductive power transfer systems with the reduction of switching devices and power losses

Several power converters have been proposed for Inductive Power Transfer (IPT) systems to generate high frequency current to excite the primary side inductive coils/tracks. This paper proposes a modified cascaded multilevel converter (MC) topology based bidirectional IPT (BIPT) system with reduced number of power electronic components and low converter losses. The proposed topology is suitable for high power - low to medium voltage IPT applications. The simulation results are presented to demonstrate the feasibility of the proposed system.
