  • Soft-switching type multiple-chip Power Device (M-Power)
    Proceedings of the 13th International Symposium on Power Semiconductor Devices & ICs. IPSD '01 (IEEE Cat. No.01CH37216), 2001

    Abstract:

    Recently Environmental consideration, such as reduction in energy dissipation, input current distortion and noise, have become necessary for switching Power supplies. To address these and the fail-safe requirements, we propose a soft-switching type multiple-chip Power Device (M-Power). The Power supply that uses M-Power satisfies energy saving, low-input current distortion and high safety demands while being compact. High efficiency is achieved by applying a novel soft-switching circuit, and low input current distortion is achieved by using a novel one-converter-type Power factor correction circuit. Low-dissipation losses while in standby mode are achieved using a standby mode control that operates at a lower switching frequency than that of normal mode. Fail-safety is achieved by various protection functions with latched shutdown.

  • pspice model of the new type Power Device n mct
    IEEE Transactions on Power Electronics, 2009
    Co-Authors: L I Huamei
    Abstract:

    MOS-controlled thyristor(MCT)is a new Power switching Device,and there isn't an accurate combination model to simulate it now.The fundamental structures of the new-type Power Device MCT is introduced.One N-MCT model is established by using the existing PSpice model library and the model's parameter is obtained with multi-transient analyzing method.Then a on-state character simulation is made on this model as well as the discharge character.The simulative results obtained are compared with the experimental results.It is seems obviously that they have the same results.

  • Computational Model of Silicon Carbide JFET Power Device
    Energy Procedia, 2012
    Co-Authors: Xiafei Hao, Sanbo Pan
    Abstract:

    This paper presents the computation simulation models for silicon carbide (SiC) vertical junction field effect Power Devices. An analytical, physics based model is capable of accurately replicating the Device behavior for the on-off state and transient conditions. The simulation results of the models were validated against measured data obtained from experiments. The current and voltage characteristics of the silicon carbide Power Device is investigated, the simulation and test results indicate that the switching transient and switching losses are improved compared with the same rated silicon Power Device. The models developed in this research effort are expected to be valuable tools for Power electronic designers in the future.
