In this article, the resonant switched-capacitor converter (RSCC) is applied to auxiliary power system of electric locomotive improve its efficiency and density. Phase shift control generally RSCC for voltage regulation. But dead time parasitic parameters impose negative effects on switching transit, resulted hard-switching process may cause extra loss. An optimized soft- realized method proposed under phase control. First, transient analysis resonance carried out by state trajectory,...

We fabricated n-type Si-based TFETs with a Ge source on Si(110) substrate. The temperature dependent IDS–VGS characteristics of TFET formed are investigated in the range 210 to 300 K. A study dependence ILeakage indicates that is mainly dominated by Shockley-Read-Hall (SRH) generation—recombination current n+ drain—Si substrate junction. ION increases monotonically temperature, which attributed reduction bandgap at tunneling junction and an enhancement band-to-band rate. subthreshold swing S...
Tacan is a military omnibearing and distance measurement system, it an important system in L-Band. As there are so many equipments work L-Band, the electromagnetic environment very complex EMC problems affect function of Tacan. In-band narrowband noise that leads to problem usually.
