Simulation Study of an Insulated Gate Bipolar Transistor With Pinched-Off N-Type Pillar

open access: yesIEEE Journal of the Electron Devices Society, 2016
This paper proposes a novel field-stop insulated gate bipolar transistor with an N-type pillar (NP-IGBT) formed on the silicon backside, which acts as a field-stop layer to pinch off electric field in the n-drift region under forward-blocking mode.

Steady-state voltage stability assessment of new energy power systems with multi-quadrant power modes

open access: yesEnergy Reports, 2023
The “source–load” attributes of the nodes in a new energy power system are complex and diverse due to a large amount of new energy access. The node power (active and reactive power) in the system can offer a changing mode, which causes several serious ...

Compensation to Fulfill Voltage Drop Security in Medium Voltage Feeders [PDF]

open access: yes, 2022
Increasing the load or expanding the feeder can increase the voltage drop. In addition, the greater the flow of reactive power on the line, the worse the voltage drop. On the other hand, the voltage must meet certain safety limits, and one way to correct
