A quantitative harmonics analysis approach for sinusoidal pulse‐width‐modulation based Z‐source inverters

open access: yesIET Power Electronics, 2022
The shoot‐through (ST) states are essential for the operation of sinusoidal pulse‐width‐modulation (SPWM) based Z‐source inverters. However, the insertion of shoot‐through state unavoidably leads to output harmonics which is greatly affected by its ...

A New Configuration of Three-Level ZSI Using Transistor Clamped Topology

open access: yesEnergies, 2020
In this paper, a three-level ZSI (impedance source inverter) based on transistor clamped theory is proposed. It uses the least number of switch counts and associated gate circuitry among all existing topologies of three-level ZSI without any performance ...

Vegetative propagation of Freesia through the isolation of shoots in vitro.

open access: yesNetherlands Journal of Agricultural Science, 1976
Shoots from the cvs Ballerina, Aurora, Rijnveld's Golden Yellow and Rose Marie, originating from excised flower-buds, were grown in vitro and were induced to form shoots on a modified Murashige and Skoog medium containing PBA and IAA. The greatest number of new shoots/excised shoot was obtained when the medium contained PBA at 5 mg/l and IAA at 0.1 mg ...

Micropropagation of Melissa officinalis L. through proliferation of axillary shoots [PDF]

open access: yesPlant Cell Reports, 1996
Multiple shoots were differentiated in cotyledonary nodes of 10 d old seedlings of Melissa officinalis, cultured on MS medium supplemented with BAP (0-4 mg/l). The production of shoots was further induced in subcultures of the original expiant, after the first harvest of shoots (stump), using similar conditions.
