A Shoot-Through Protection Scheme for Converters Built With SiC JFETs
IEEE Transactions on Industry Applications, 2010The SiC JFET is an attractive semiconductor device due to its superior switching performance and high-temperature operating capability. Its shoot-through protection remains a challenge due to the limited practical knowledge existent on this device and due to its inherent normally on nature.

Shooting Through Clothing in Firearm Suicides
Journal of Forensic Sciences, 2010Abstract: There is a longstanding empirical rule that people who commit suicide rarely shoot through their clothing, but rather put it aside to expose the nude skin. Signs of shots through clothing have always been considered suspicious, raising presumptions of the presence of an abettor.

Unusual attempted suicide by shooting through heart
Forensic Science International, 2005Gunshot wounds in the heart are frequent suicidal injuries, especially in men. Most of them are lethal, but some cases of survival due to immediate and proper surgical treatment are reported. However, survival without specific treatment is extremely rare. In our case, a 44-year man attempted suicide by home-made shooting device.

Detection of pneumothorax with lateral shoot-through digital radiography
Clinical Radiology, 1993The aim of this study was to compare the performance of digital frontal radiographs vs digital lateral shoot-through radiographs for the diagnosis of pneumothoraces in supine patients. A total of 146 pairs of radiographs were performed on 32 ventilated patients on the Intensive Care Unit.

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

Active thermal control by controlled shoot-through of power devices
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017Active Thermal Control (ATC) consists in driving power switches in a less efficient way when low load conditions are present. The resulting wasted power is used to self-heat the device, reducing amplitude and occurrence of thermal cycles and hence improving the reliability.

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 ...

Three‐phase common‐ground‐type photovoltaic inverter without shoot‐through problem
International Journal of Circuit Theory and ApplicationsSummarySince there are common mode leakage current (CMLC) and shoot‐through problems in the conventional three‐phase transformerless photovoltaic (PV) inverters, the three‐phase common‐ground‐type transformerless dual‐buck inverters (DBIs) are derived. By shorting the neutral point of the three‐phase load and the negative terminal of the PV panel, the ...
