چکیده

A new wide voltage operation range isolated battery charger, which is composed of an asymmetric T-type AC–DC power rectifier and a modified re-configurable half bridge DC–DC converter, proposed in this paper. The adopts different modulation strategies under AC bus amplitudes voltages for increasing conversion efficiency. As the stage, converter applies three-winding transformer to achieve output range. charger operates over input DC 3.2 kW hardware prototype built adapt between 85 265 V. Both constant current modes are implemented experimentally charge up 6.5 from 50 500 experimental results prove that can increase efficiency, V around 94%

A Zvs Full Bridge Resonant Inverter Based High Step down Multiple Output Converter with Wide Input Voltage Range

DC-BUS based power distribution systems with battery backup have been widely used in aerospace and telecommunication applications, where the bus voltage is usually determined by the battery. In these systems, there are many loads that need different and low operating voltages. Since the bus voltage is usually much higher than the load voltage and varies in a wide range with the stage of charge ...

A Family of Magnetic Coupling DC–DC Converters With Zero-Voltage-Switching Over Wide Input Voltage Range and Load Variation

This paper presents a family of soft-switching DC–DC converters with a simple auxiliary circuit consisting of a coupled winding and a pair of auxiliary switch and diode. The auxiliary circuit is activated in a short interval and thus the circulating conduction losses are small. With the auxiliary circuit, zero-voltage-switching (ZVS) and zero-current-switching are achieved for the main and auxi...

On electric vehicle battery charger modeling

The increase of electric vehicle (EV) battery chargers connected to electric networks could lead to future harmonic problems in power systems. These loads are nonlinear devices that inject harmonic currents and pollute network voltages. Thus, battery charger modeling must be studied in detail to determine their harmonic emissions and prevent future problems. This paper investigates EV battery c...
