Medium voltage dc converters with multiple output ports have the challenges of series input module power balancing control and fault isolation between ports. This article proposes a new medium multiport isolated transformer topology. The proposed topology can be extended to up 2 k-1 different voltages k modules connected in series. Moreover, has self-balancing feature since they are coupled via capacitors. Current all <sc xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Abstract A new dual kiln processing route has been proposed and investigated for removal of heavy metals from the zinc-rich fraction blast furnace (BF) sludge recovery ferrous materials. The zinc in BF exists both as ZnO ZnS. thermodynamic analysis indicates that carbochlorination shows a selective metal removal. Lead can be removed at temperature below 900°C followed by higher temperatures, producing an iron-rich clean residue free end feasible recycling back to ironmaking. High experiments...
Pot experiment was conducted with the cutting seedlings of Ilex kudingcha C. J. Tseng. By adding lead, copper solution and self-exist zinc in soil, we research for phytoavailability heavy metal different soil situation. The characterization methods were investigated. Results show that are strong absorption elements from BAC (Biological Absorption Coefficient) averages 13 groups experiment. order is lead > zinc. 0.05mol/L EDTA-2Na can be used as extracting agent or copper, 0.1mol/L HCl...
Based on the field investigation and sampling, seven dominant wild plants relative soil samples in Hainan Shilu iron mines area were collected. To analyze study contents of heavy metals Pb, Cd, Cu, Fe, Mn Zn these characteristics enriching plants. Results this showed that same metal soils around roots system had a large range variation, to certain extent, it reflected difference enriched different metal. All endurance Fe. Bothriochloa root hoarded up abundant its stored Mn, Cd also stood out...
A method to reconstruct the acoustic far-field using a semi-circular sensor array is proposed. Firstly, pressures in are measured by array; then, reconstructed based on theory of radiation modes. The numerical simulations for reconstructing baffled rectangular plate conducted. results show that can be accurately few sensors array. influence noise reconstruction field analyzed, and robustness proposed proved. This paper provides through simple measuring applied large structures, has good...
The input series output parallel (ISOP) converter system faces the challenge of complex power balancing control. In this article, a switched capacitor based multi-port DC with self-balanced capability is proposed. Based on switched-capacitor principle, capacitors periodically charge and discharge to balance voltage capacitors. Furthermore, by introducing LC coupling circuit, impedance each branch adjusted current switch. Finally, simulation 3kV input, S00V/1kW S0V/1kW performed. Simulation...
The series resonant converter (SRC) is one of the most popular galvanically isolated dc–dc converters since it provides zero voltage switching (ZVS), reduces rms currents, using transformer leakage inductance as can further reduce volume converter. However, in medium-voltage (MV) grid to low-voltage (LV) DC bus applications, order meet transformer's high insulation strength and power requirements, parasitic capacitance large, causing resonance current oscillations spikes. equivalent circuit...
