As the usage of cell phones is markedly increasing worldwide, accidental injuries and even lethal damages caused by cellular phone explosions have been reported lately. Although, cell phone charger explosion related scalding and tissue loss is extremely rare, they generally cause severe damage to tissues and cause severe complications, ending up in hospitalization. We are presenting a case of 9...

─ This paper presents a voltage doubler in to a half bridge converter is derived for electric vehicle battery chargers. The proposed converter provides wide ZVS range, reduced circulating current and also voltage stress. Circulating current during the freewheeling phases of phase shift full bridge circuit are reset by the sum of LLC circuit output voltage and resonant capacitor voltage by achie...

The Long Life (Lithium Ion) Battery (LLB/LIB) is designed to replace the current Extravehicular Mobility Unit (EMU) Silver/Zinc (Ag/Zn) Increased Capacity Battery (ICB), which is used to provide power to the Primary Life Support Subsystem (PLSS) during Extravehicular Activities (EVAs). The LLB (a battery based on commercial lithium ion cell technology) is designed to have the same electrical an...

A DC-DC converter that can be applied for battery chargers with the power-capacity of over 7-kW for electric vehicles (EVs) is presented in this paper. Due to a new architecture, the proposed converter achieves a reduction of conduction losses at the primary side by as much as 50% and has many benefits such as much smaller circulating current, less duty-cycle loss, and lower secondary-voltage s...

The charging method has a significant influence on the performance and lifetime of Rechargeable batteries. Therefore intelligent charging algorithm which can properly determine the charging current is essential. In this study, a fuzzy-logic-control-based (FLC-based) battery charger is proposed. The proposed charger takes the voltage and current of battery into account, and adjusts the pwm duty ...

Lithium ion (Li-ion) batteries have been widely used in various kinds of applications, including consumer electronics, green energy systems and electrical vehicles. Since the charging method has a significant influence on the performance and lifetime of Li-ion batteries, an intelligent charging algorithm which can properly determine the charging current is essential. In this study, a fuzzy-logi...

Call forwarding is a traditional telecom service that allows a user to forward incoming calls to another telephone number. This service requires the user to manually activate and deactivate the feature and therefore may not be very convenient. This paper proposes an automatic call-forwarding algorithm (CFA) for mobile phones. By installing a software in a smartphone, call forwarding is automati...
