VOLTAGE-DOUBLE MAGNETICALLY COUPLED IMPEDANCE SOURCE NETWORKS

ABSTRACT:

 A family of voltage-double magnetically coupled impedance source networks (VBMCISNs) is presented. The scheme of the proposed family is that adding the auxiliary capacitors and diodes to the magnetically coupled transformers to realize the voltage-double function. The proposed impedance networks can produce the higher voltage gain, reduce the voltage stresses across the passive components, have a common ground, realize the continuous input current and suppress the start-up inrush current. Finally, one of the resulting topologies is verified in the condition of DC-DC converter and DC-AC converter, theoretical analysis and experimental results are offered to verify the topology’s validity.

A HYBRID BI-DIRECTIONAL WIRELESS EV CHARGING SYSTEM TOLERANT TO PAD MISALIGNMENT

A HYBRID BI-DIRECTIONAL WIRELESS EV CHARGING SYSTEM TOLERANT TO PAD MISALIGNMENT

ABSTRACT:

              Electric vehicles (EVs) are becoming increasingly popular as a means of future transport for sustainable living. However, wireless charging of EVs poses a number of challenges related to interoperability, safety, pad misalignment etc. In particular, pad-misalignments invariably cause changes in system parameters which in turn lead to increase in losses as well as reduction in power throughput, making the charging process long and inefficient. Consequently, wireless charging systems that are less sensitive to pad-misalignments have become preferable. This paper, therefore, presents a hybrid Wireless Power Transfer (WPT) system that charges EVs at constant rate despite large misalignments between charging pads. The proposed charging system uses a combination of two different resonant networks to realize a constant and efficient charging process. A mathematical model is also

POWER ROUTING FOR CASCADED H-BRIDGE CONVERTERS

Modular power converters are expected to play a major role in medium and high voltage/power applications. Normally, each module processes the same amount of power, however this does not take into consideration that different modules can have a different remaining useful lifetime. This paper proposes the concept of power routing for cascaded H-bridge (CHB) converters, with the purpose of delaying the failure of the system. A third-harmonic injection into the duty cycles allows extending the imbalance capability of the structure, keeping the CHB operational even if some power paths are completely unloaded. Analytic investigation in conjunction with simulation and experimental measurements demonstrate the power routing by means of the proposed method.
