This manuscript proposes a novel and simple integrated rectifier-inverter converter topology to handle electric power exchange between generator or alternator, utility (for plug-in charging) and electric motor in light plug-in hybrid electric vehicles (LPHEV). The power system of PHEVs can be three-phase or single-phase based on overall system power capability, requirements or design criteria; however,...
In this paper, a novel loads multiplexing topology is proposed in order to obtain a cost effective solution, presenting high efficiency, high utilization factor of electronics, and a reduction in the system components. The topology based on two half bridge inverters and they are multiplexed for feeding four loads using six SPDT (single pole double throw electromechanical relay), also the same topology...
Large deployments of Distributed Generators (DGs) have substantial impacts on the structure of existing networks. In order to tackle these issues, it has been proposed to divide the network into smaller manageable sets which can be more effectively and efficiently operated. This very concept is called the `Microgrid'. However, due to their unprecedented structure, these smaller grids experience very...
This paper presents a modified topology of the neutral-point-clamped inverter suitable to increase the converter reliability in safety-critical applications. With the proposed scheme, the energy processing capacity can be maintained even for multiple failure modes. Its fault-tolerant ability results from redundancy of power devices and from modifications in the control strategy. The theoretical validity...
This work is intended to describe a novel topology for a class E oscillator for induction heating in cooking applications. The topology is remarkable for low cost, low size and medium-high power applications where efficiency is a must. Experimental results for a 900W (92% efficiency) prototype are included. Multiple-burner induction cooking system including three or four inductors is widely present...
In this paper, a generalized multiband hysteresis modulation and its characterization have been proposed for the sliding-mode control of cascaded H-bridge multilevel-inverter (CHBMLI)-controlled systems. A frequency-domain method is proposed for the determination of net hysteresis bandwidth for a given desired maximum switching frequency of the inverter. The switching transition concept of Tsypkin's...
Future automobiles will be equipped with by-wire systems to improve reliability, safety and performance. The fault tolerant capability of these systems is crucial due to their safety critical nature. Three fault tolerant inverter topologies for permanent magnet brushless dc motor drives suitable for automotive x-by-wire systems are analyzed. A figure of merit taking into account both cost and post-fault...
