This paper presents a new single inductor Dual Input-Dual Output dc-dc converter for a standalone hybrid energy system. The converter has two unidirectional ports, one bidirectional port for storage element and one output port. The converter operates in dual input-dual output mode, dual input-single output mode and single input-single output mode. Both the input sources can power up the load individually...
This paper presents the development of an electric skateboard and with a flyback switch-mode rectifier (SMR) based battery charger. An interleaving DC/DC buck converter-fed DC motor is established and used as the propulsion actuator of the skateboard. Thanks to the interleaving approach, the armature current ripple is reduced, and the fault tolerance of power circuit is preserved due to the redundancy...
In this paper, a closed-loop control of isolated bidirectional dual active bridge (DAB) DC-DC converter is proposed using dual phase shift (DPS) modulation. The DPS technique can decrease reverse current flow, reduce current stress and improve the system efficiency as compared to traditional phase shift (TPS) control. The detailed operating waveforms of the DAB converter using DPS technique are illustrated...
In this paper a novel multi-purpose converter for electric vehicles (EVs) is proposed. This topology, optimized for a full electric drive, satisfies propulsion requirements and allows single phase as well as three-phase AC charging. As compared with the onboard integrated chargers on the market today, this topology enables significant cost, weight and volume reductions. The proposed topology is theoretically...
In this paper, a single stage highly efficient photovoltaic grid interconnected charging infrastructure has been designed for off-board DC charging for electric vehicles. This paper starts with the design of a single phase H-bridge quasi-z-source inverter (qZSI), component design and the pulse width modulation technique used. Then it discusses the control techniques used to control the power flow...
