Wide-scale adoption and projected growth of electric vehicles (EVs) necessitate research development power electronic converters to achieve high power, low-cost, reliable charging solutions for the EV battery. This paper presents a comprehensive review off-board chargers that consist ac-dc dc-dc stages from network Although are categorized into two types, namely, on-board chargers, it is essent...

We previously showed that a premature stimulus can significantly alter vulnerability to arrhythmias by modulating spatial gradients of ventricular repolarization (ie, modulated dispersion). However, it is not clear if such changes in arrhythmia vulnerability can be attributed to the formation of an electrophysiological substrate for unidirectional block and what the potential role is of tissue ...

Electric Vehicles (EVs) are becoming increasingly available and expected to be a large part of the load in future power systems. EV chargers relatively new type mainly interfaced with grid through electronics. It is therefore important investigate impact they have on system dynamic behaviour. In this paper, two detailed charger models (representing typical slow fast charger) were investigated. ...

Wireless energy transfer is a promising technology to prolong the lifetime of wireless sensor networks (WSNs), by employing charging vehicles to replenish energy to lifetime-critical sensors. Existing studies on sensor charging assumed that one or multiple charging vehicles being deployed. Such an assumption may have its limitation for a real sensor network. On one hand, it usually is insuffici...

A computer model of a ring-shaped, one-dimensional cardiac fiber was used for examination of responses of propagation to premature stimuli applied under different degrees of both cell-to-cell coupling and membrane excitability. Results demonstrated the importance of cellular uncoupling in the genesis of unidirectional block and reentry. Propagation of excitation itself created a certain degree ...

The transportation industry now accounts for approximately a quarter of worldwide energy-related direct CO2 emissions, and governments all around the globe have committed to converting their fossil-fuel vehicles zero-emission ones by adopting electric vehicles. Current (EV) can store 18 100 kWh energy, which may be employed not only commuting but also other purposes such as delivering energy ho...

This paper introduces a versatile control scheme for unidirectional ac–dc boost converters using fuzzy logic controller for the purpose of mitigating grid power quality. Since most power factor correction circuits available in the commercial market utilize unidirectional ac– dc boost converter topologies, this is an almost nocost solution for compensating harmonic current and reactive power in ...

The unidirectional acoustic boundary has a broad application prospect. Besides the acoustic metamaterial or the strongly nonlinear acoustic medium, which were applied in the realization of the unidirectional acoustic boundary, the present paper proposes another approach through the active control method, where the control source has the property of single directivity. In order to validate its e...
