Usually a LLC resonant converter is used in applications with high input voltage (300-400 V) and low output voltage (48-60 V). This type of converter includes a half bridge topology and is only designed for unidirectional power transfer. Since the benefits of a LLC resonant converter are high efficiency, high power density and low EMI, it is a very interesting topology for vehicular applications....
This paper presents a novel resonant dc-dc converter using Z-source impedance network. The conventional series resonant converter suffers from efficiency degradation problem when the input voltage range is wide because the switching frequency of converter should be increased far away from resonant frequency to control output voltage. The proposed Z-source resonant dc-dc converter can minimize switching...
In order to improve the performance of switched reluctance motor (SRM) drives, some advanced control strategies have been proposed, such as current or flux linkage profile control. To achieve these strategies the motor phase current or phase flux linkage should be controlled precisely. All these require increasing the switching frequency of converter to upgrade stability and dynamic response speed...
