Abstrakt

In this paper a DC-link voltage balancing strategy for multilevel Cascaded H-Bridge (CHB) converter is proposed. Presented solution bases on optimal choice of active vector durations in Space-Vector Pulse Width Modulation (SV-PWM). It makes it possible to DC-link voltages control and to properly generate the output voltage vector in the case of DC-link voltage unbalance. Results of simulation and experimental researches on proposed control strategy are presented in the paper.

Abstrakt

The article is devoted to contemporary studies on the nineteenth century memoirs written by Russian women. In the nineteenth century women’s memoirs were underestimated and neglected by researchers. Recently, there has been a signifi cant increase in research interest in memoirs written by women. This subject has been taken up by literary scholars, historians, experts on cultural studies and anthropologists. A. Bielova, I. Savkina, W. Laszczak, K. Kosowska, N. Pushkariova, A. Fieduta, W. Ponomarieva, L. Khoroshilova, J. Prikazchikova, A. Stankewich, J. Samofalova, O. Mamaieva, S. Tatarkina are among those who are interested in it. Memoirs are a valuable source of information about the epoch, historical events, outstanding leaders, event-making fi gures, Russian intellectual elites, aristocracy as well as the everyday life of the Russian gentry. They also provide some insight into the way female memoirists expressed themselves in their writings, their views on femininity and the role of women in society.
