A Generalized Phase-Shift PWM Extension for Improved Natural and Active Balancing of Flying Capacitor Multilevel Inverters by Georgios Kampitsis, Efstratios I. Batzelis, Antonis Kolokasis, Elison Matioli, Bikash C. Pal

“…The alternative of <italic>active balancing</italic> normally requires one isolated sensor per FC which increases the overall system cost and footprint, or a single ac-side sensor that is more compact but calls for sophisticated PWMs that again are not available for multiple levels. In this paper we introduce a generalized pulse width modulation (PWM) strategy based on the phase-shift and carrier swapping principles for an arbitrary number of levels. …”

The development of triploid apple cultivars is a priority in breeding by E. N. Sedov, G. A. Sedysheva, M. A. Makarkina, Z. M. Serova

“…It should be noted that sometimes donors of diploid gametes with necessary important traits not only have to be selected from among existing tetraploid cultivars, but also developed by a breeding way, especially in the case when in nature there are no cultivars and genotypes (donors of diploid gametes) with given traits. The authors of the paper developed form 30-47-88 (Liberty×13-6-106) by a breeding way. 30-47-88 is a complex donor of diploid gametes and scab immunity (Vf ) at once. …”
