| Abstract |
In this paper, a simplified enough topology which is used as a battery charger for electric
vehicles is investigated. The proposed topology is based on the flyback converter. Since the basic
problem of this type of converter is the overvoltage across the main switch during the switch-off, a
newly developed active clamp circuit is presented. This active snubber is based on the flyback
topology and has some important advantages compared to other types of active clamping topologies.
Also, a new improved approach for the main converter design strategy is presented. The strategy is
focused on the choice of an optimal transformer turns ratio by taking into account the overvoltage
across the main switch. Finally, simulation and experimental result are exhibited and compared,
proving the effectiveness of the design methodology. |
