A Technique for Improving the Precision of the Direct Measurement of Junction Temperature in Power Light-Emitting Diodes

open access: yesSensors, 2021
Extending the lifetime of power light-emitting diodes (LEDs) is achievable if proper control methods are implemented to reduce the side effects of an excessive junction temperature, TJ. The accuracy of state-of-the-art LED junction temperature monitoring

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 ...

Ultra Low Loss Trench Gate PCI-PiN Diode with VF<350mV [PDF]

open access: yes, 2011
PiN diode forward voltage drop was reduced to as low as 325mV by the pulsed carrier injection (PCI) mechanism with trench MOS gate as the integrated injection control switch. The conventional PiN diodes have voltage drop of about 0.8V which is equivalent
