TL;DR: In this article, an experimental and 2D simulation investigation showed that latchup is involved in the triggering of the N-channel power IGBT, which is the first time that latch-up has been shown to be involved in triggering the device.
Abstract: Heavy ion induced destructive failures are reported in N-channel power IGBTs. For the first time, an experimental and 2D simulation investigation shows that latchup is involved in the triggering of the device.

TL;DR: This work focuses on demonstrating a small form factor, high efficiency offline LED driver using GaN FETs with an integrated gate driver and controller circuit implemented on a 0.35μm CMOS process with 3.3V/15V voltage handling capability.
Abstract: With the advent of reliable, high brightness and high efficacy LEDs, the lighting industry is expected to see a significant growth in the near future. However, for LEDs to completely replace the traditional incandescent and CFL bulbs, the power converters within the LED drivers need to be miniaturized. Superior figure of merit (Rds,ONxQg) of Gallium Nitride (GaN) FETs over Silicon FETs [1] can enable both high efficiency and high frequency operation, thereby making power converters smaller, more efficient and reliable. By using integrated controllers and drivers, the number of components on the driver PCB can be reduced, further miniaturizing the driver. This work focuses on demonstrating a small form factor, high efficiency offline LED driver using GaN FETs with an integrated gate driver and controller circuit implemented on a 0.35μm CMOS process with 3.3V/15V voltage handling capability.

09 May 1999TL;DR: In this paper, a reliable configuration for triggering a series string of power MOS devices without the use of transformer coupling is presented, where a capacitor is inserted between the gate and ground of each MOSFET.
Abstract: A reliable configuration for triggering a series string of power MOS devices without the use of transformer coupling is presented. A capacitor is inserted between the gate and ground of each MOSFET, except for the bottom MOSFET in the stack. Using a single input voltage signal to trigger the bottom MOSFET, a voltage division across the network of device capacitance and inserted capacitances triggers the entire series stack reliably. Design formulae are presented and simple circuit protection is discussed. Simulation shows reliable operation and experimental verification is presented. Application of the method is applied to series IGBTs.

TL;DR: In this paper, the authors proposed a pixel division structure for a liquid crystal display with a pixel-division structure, where a pixel includes a first subpixel having a first luminance and a second subpixel with a second luminance, which is different from the first one.
Abstract: A liquid crystal display device according to the present invention includes an LCD panel 10 including a liquid crystal layer, electrodes for applying a voltage to the liquid crystal layer, and a pixel, of which the luminance varies according to a display signal voltage supplied through a transistor. The pixel includes a first subpixel to have a first luminance and a second subpixel to have a second luminance, which is different from the first luminance, in response to at least one display signal voltage supplied. The device further includes: a source driver 40 for supplying the display signal voltage to a source bus line connected to the source of the transistor; a gate driver 30 for supplying a scan signal voltage to a gate bus line connected to the gate of the transistor; and luminance switching circuitry 60 for switching a first mode, in which the first luminance is higher than the second luminance, into a second mode, in which the first luminance is lower than the second luminance, or vice versa, thereby increasing the reliability of a liquid crystal display device with a pixel division structure.

TL;DR: A solution to provide self protection in a normally-On JFET voltage fed inverter using Normally-On devices is proposed, a plug-in to an existing Gate driver.
Abstract: In this paper, the authors propose a solution to provide self protection in a normally-On JFET voltage fed inverter. The solution is a plug-in to an existing Gate driver. An overview of JFET Gate driving serves as an introduction to the problem of self protection of inverters using Normally-On devices.
