— In this paper, the indirect matrix converter is systematically studied with the single-pole-multiple-pole representation. A carrier based PWM algorithm is developed in two steps. First, the continuous modulation functions for all the throws are derived based on the desired sinusoidal input currents. Then the switching functions are derived from the(More)
—The reliability prediction of hybrid electric vehicles (HEVs) is of paramount importance for planning, design, control, and operation management of vehicles, since it can provide an objective criterion for comparative evaluation of various configurations and topologies and can be used as an effective tool to improve the design and control of the overall(More)
This paper presents a new topology of a three-phase dynamic voltage restorer (DVR) that is based on an ac-ac power converter. Two different operations of realizing of the ac-ac converter are proposed in accordance to the application requirement whether phase shift is involved in the output voltage with respect to the input voltage. For inphase compensation,(More)
Causing potato brown rot, Ralstonia solanacearum (R. solanacearum) strains are reported as one of the most destructive bacteria to potato (Solanum tuberosum L.) in China. In this study, 113 strains were isolated from potato, collected in the four major agroecological zones in China. The study showed that 102 strains belonged to the phylotype IIB sequevar 1(More)

— Conventional modulation strategies for matrix converters based on trigonometric transformations and space vector techniques have their voltage transfer capability limited at about 0.866 p.u. This leads to a derating of motor capability by 25% in the realization of variable frequency drives using off-the-shelf line-fed motors, or requires custom designed(More)
