Analysis of Dynamic Charging Performances of Optimized Inductive Power Transfer Couplers

This paper aims to investigate the dynamic charging performance of an 11 kW dynamic inductive power transfer (DIPT) system. First, a multi-objective optimization (MOO) method is proposed to find the Pareto front of the DD charging pad. Then, the optimal design with a 96.82% efficiency is selected as the target design for the DIPT system....

Electric Vehicle Charging with Multi-Port Converter based Integration in DC Trolley-Bus Network

DC traction networks that supply power to trolley-buses, tramcars and trains can be simultaneously used to integrate fast-charging stations for Electric Vehicles (EVs). This strategy improves the traction grid utilization of urban transportation systems. In addition, it offers a potential solution to the increasing requirement of charging...

Design of Misalignment Tolerant Control for an Inductive Charger with V2G Possibilities

Since the power transfer efficiency in inductive power transfer (IPT) systems is directly related to the coupling of the transformer, coil misalignment can drastically decrease the efficiency.

Power Flow Decoupling Controller for Triple Active Bridge Based on Fourier Decomposition of Transformer Currents

This paper proposes a power flows decoupling controller for the triple active bridge converter. The controller is based on a full-order continuous-time model of the TAB converter derived using the generalized average modelling (GAM) technique. GAM uses the Fourier series expansion to decompose the state-space variables into two components,...
