“…In the SDSR, the gate signals are generated directly by the transformer auxiliary windings [5], [6]. Compared with gate driving methods which are using ICs, SDSR decreases the design complexity, production cost, elements number and gate driving loss [7], [8], [9]. A problem is the malfunction of SDSR in converters using dead time to regulate output voltage.…”

“…This paper presents a novel converter which benefits from zero-voltage switching, resonance, isolation, integrated transformer and self-driven synchronous rectifier for lowvoltage high-current applications. Profiting from advantages of high efficiency, low switching, conducting and thermal losses, low EMI and gate driver loss, small size, high switching frequency range and isolation, this converter can be applied in various applications such as domestic electronic appliances, LED power sources, battery charging purposes, inductivelyheated appliances, wireless power charging of portable electronics, transcutaneous power transfer systems, biomedical implants, photovoltaic power optimizer, telecom and other centralized modular and distributed power applications [2], [7]. Furthermore, low-voltage high-current power electronic converters have received huge interest of both industry and academia for their application in stand-alone electric power generating systems.…”

In this paper a step-down ZVS power converter with a self-driven synchronous rectifier (SDSR) for a low-voltage high-current applications is proposed. A transformer leakage inductance, a resonant capacitor and a diode make up the active resonant network. To improve the performance of the converter, a SDSR with a center-tapped transformer is used at the secondary side of the converter. Consequently, due to transformer leakage inductance in secondary side, the output section requires no additional inductor, leading to a major size reduction of the circuit. For verification purposes, a laboratory prototype of the proposed converter is manufactured. Experimental results are presented for waveforms to validate the theoretical outcomes. Additionally, to substantiate the design of the proposed converter, a laboratory prototype is manufactured.

“…11,12 Driven by environmental awareness and the price of fossil fuel, the use of electric vehicles (EVs) is growing, and EVs are becoming increasingly available for consumers and businesses alike. 7,13,14 In 2011, the US government set the goal that 1310 6 EVs will be on the US roads by the year 2015. 15 However, the major obstacle for widespread use of EVs is the battery, which cannot support a long travelling range in comparison with that of gasoline vehicles.…”

Wireless power transfer is a promising method to address the concerns over charging an electric vehicle. Since wireless charging stations operate without large cables or above-ground stations, they can be conveniently installed in public locations without the risk of vandalism or weather-inflicted damage, improving the lifespan of the electric vehicle charging station. In order for wireless charging stations to become widespread, possible health effects regarding exposure to the strong electromagnetic fields present during wireless power transfer must be investigated. This work examines, first, the potential human safety hazards, second, the electronic device interference, and, third, the thermal heating effects of wireless charging systems. A 3.3 kW wireless power transfer prototype was built in order to examine these effects. Changes in the wireless power transfer efficiency due to the coil misalignment were also investigated using an automated three-axis platform. Design considerations for electric vehicle wireless charging systems and safety recommendations are presented.
