This paper describes a power electronic system that, among other possibilities, can be used to charge electric vehicle batteries. A large-signal linear, multirate digital controller for the charging current permits the charger to track and deliver a desired current trajectory for a wide range of loads. This controller simultaneously ensures that the charger draws power from the electric utility...

Battery-charger demands have changed from a simple stand-alone charger to an embedded charger and power source for the system. This topic provides some insight into the many new issues the designer should consider when designing either a linear or a switching regulator. Common transient issues caused by hot plugging/unplugging the adapter or system load during operation are presented. Problems ...

Stage bus operated in the mixed traffic might always meet many problems about low quality and reliability of services. The low quality and reliability of bus service can make the system not attractive and directly reduce the interest of using bus service. This paper presents the result of field investigation and analysis of on-time performance and service regularity of stage bus in mixed traffi...

All kinds of mobile phone chargers in the actual use process, due to poor quality products or improper will cause safety accidents, causing great harm, so this paper has practical significance study risk and accident causes chargers. First all, through failure insulating materials between conductive parts charger, substandard artificial plug-ins production components, waste circuit boards board...

A new integrated power electronics interface (IPEI) for battery electric vehicles (BEVs) in order to optimize the performance of the power train is proposed in this paper. As Power electronics interfaces plays important role in the automotive vehicle technologies the proposed IPEI is responsible for the power-flow management for each operating mode. The operating modes will explain how IPEI wor...

In this paper, we investigate the mobile charging in rechargeable sensor networks. By utilizing the historic charging information, the mobile charger can prefetch the charging requests from sensor nodes before they are sent out, and thus both the charging latency of sensor nodes and the travel distance of mobile charger can be reduced. Furthermore, by controlling the amount of energy to charge ...

Electrification of the transportation sector has originated a worldwide demand towards green-based refueling infrastructure modernization. Global researches and efforts have been pondered to promote optimal Electric Vehicle (EV) charging stations. The EV power electronic systems can be classified into three main divisions: station configuration (e.g., Level 1 (i.e., slow-speed charger), 2 fast-...

A power management controller circuit with a switched-capacitor mode down-regulator and a battery charger block for semi-active radio-frequency identification (RFID) tags was proposed and fabricated. The major achievement of the proposed switched-capacitor mode downregulator and battery charger block is providing a low standby current internal voltage supply circuit and self-controlled thin fil...
