In this paper, the properties and operation of virtual-space-vector pulse-width modulation (PWM) for a three-level neutral-point-clamped inverter with unbalanced dc-links are studied. By quantitatively analyzing characteristics revised space-vector diagram (SVD) dc-links, defined virtual SVD (VSVD) case is theoretically proven identical to VSVD conventional PWM (VSVPWM) strategy balanced dc-links. The well-developed fast-processing methods calculate durations nearest three vectors VSVPWM can...
The phytoremediation performance of Mentha Aquatic, Typha Orientails Presl, Tagetes Patula L. and Iris Tectorum Maxim was investigated by pot experiments to remediate the heavy metal contaminated sediment added with 1‰, 3‰, 5‰ humic acid (HA), respectively, over 60 days. results showed that four hydrophytes could get a better accumulation for Cd, Cu, Pb, Ni from sediments 3‰ HA as amendment. While, got maximum amount Pb As Maxim, optimum addition accumulate 10% increase compared control...
Low-rank coals, biomass, and heavy petroleum are typical carbon resources, which currently not efficiently used, many processes for the current use of resources cause severe environmental pollution with very limited economic benefits even a great deficit. Efficiently using can greatly improve environment create huge benefits. The main difficulty in is high content aromatic rings (ARs) heteroatoms addition to insoluble complex macromolecular structures resources. Catalytic hydroconversion...
The dc links of the three-level neutral-point-clamped (3L-NPC) converter are needed to work in imbalanced state some special fields, and a hybrid pulsewidth modulation (PWM) strategy this case is studied paper. proposed combination space-vector PWM carrier-based (CBM) method. characteristic revised diagram (RSVD) with unbalanced from new perspective, based on it, novel sector distribution method identify utilized switching sequences. Instead calculating durations adopted space vectors...
This paper aims to study the characteristics of greenhouse gas (GHG) emissions from heavy-duty trucks in Beijing-Tianjin-Hebei (BTH) region, which is located Northern China. The multiyear GHG (CO2, CH4 and N2O) fueled by diesel natural during period 2006–2015 were compared analyzed. results show that increase with time, consistent trend population growth. total amount carbon dioxide equivalence (CO2e) BTH region was about 5.12 × 106 t 2015. Among three sub-regions, Hebei possesses largest...
