An Adjustable Sensorless Shoot-Through Protection for H-Bridges
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018The converters relying on H-bridge configurations exhibit complementary “symmetrical” switching devices for which a triggering dead-time must be considered in order to prevent shoot-through faults. There are two ways in which such dead-time is usually added to the bridges' input signals; namely, from the switching program itself, and by using dedicated

IGBT half-bridge shoot-through characterization for model validation
IAS '96. Conference Record of the 1996 IEEE Industry Applications Conference Thirty-First IAS Annual Meeting, 2002A circuit is described for making a variety of measurements on half-bridge insulated gate bipolar transistor (IGBT) pairs for validating IGBT models. The circuit incorporates two robust isolated gate drives for the IGBTs. Each IGBT is driven with an eight-cycle square-wave burst with a long dead-time between bursts so that heat-sinking requirements are

Potential to prevent mass shootings through domestic violence firearm restrictions
Criminology & Public Policy, 2019Research SummaryWe investigated the extent to which the 89 mass shooters who committed their acts from 2014 through 2017 were known or suspected to commit domestic violence prior to the shooting, whether they had been engaged in the justice system in a way that could have led to domestic violence firearm restrictions, and why they were either not ...

A shoot-through protection scheme for converters built with SiC JFETs
2009 IEEE Energy Conversion Congress and Exposition, 2009SiC JFET has been an attractive device for the converter construction due to its superior switching performance and high temperature operation capability. But the shoot-through protection remains a challenge because of the limited knowledge and normally-on characteristics of this device. This paper presents a novel shoot-through protection approach.

A Doubly Grounded Transformerless PV Grid-Connected Inverter Without Shoot-Through Problem
IEEE Transactions on Industrial Electronics, 2021As conventional transformerless PV grid-connected inverters have shoot-through problem and common mode leakage current issue, a doubly grounded transformerless PV grid-connected inverter is proposed. The proposed inverter consists of a buck converter and a buck–boost converter, which operates at positive and negative half-line cycles, respectively ...

Active overcurrent protection schemes in bridge inverters operating under shoot-through conditions
2015 International Conference on Power, Instrumentation, Control and Computing (PICC), 2015The following paper proposes two overcurrent protection schemes that are applicable for limiting the current through the main switching devices in Bridge type Inverters under shoot-through conditions. Under normal mode of operation, the high side and low side switches of the bridge converters conduct on alternate half cycles.
