Both Hybrid Electric Vehicles (HEVs) and Electric Vehicles (EVs) need a traction motor and a power inverter to drive the vehicle motor. The requirements for the power inverter include high peak power, low output harmonics, inexpensive circuit and low continuous power rating. In this paper, reducing the output harmonics of cascade H-bridge multilevel inverter for electric vehicle applications is proposed...
This paper presents a novel fully soft switched bidirectional PWM dc-to-dc. Providing soft switching conditions for all elements and minimizing the semiconductor elements are two of the most important properties of this converter. The proposed bi-directional converter is inserted as an interface circuit between DC bus and battery in a Hybrid Electric Vehicle to control the charge and discharge current...
The trade-off between pedestal error and acquisition time limits the level of speed-accuracy that can be achieved by CMOS track-and-hold circuits. This paper presents a circuit technique to design a high-resolution, high-speed T/H circuit. The sampling error produced by clock feedthrough and the charge injection of CMOS switches are eliminated through a cancellation technique using a replica circuit...
VLANs offer significant benefits in terms of efficient bandwidth, flexibility, performance and security by logically segmenting the network into different broadcast subsets which switch packets merely between the designated ports of the same VLAN. Spanning tree protocol (STP) is extensively used in active topology configuration of VLANS. This protocol prevents from layer 2 loops in networks by breaking...
