#snsinstitutions #snsdesignthinking #snsdesignthinkers #snsct #snsmct TRANSISTOR A transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics.[1] It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more in miniature form are found embedded in integrated circuits. Because transistors are the key active components in practically all modern electronics, many people consider them one of the 20th century's greatest #snsinstitutions

Characterizing power switches is an indispensable step when designing a converter. This thesis investigates ways to achieve static and dynamic characterization of semiconductors for high power applications such as power grid or train traction. The static characterization has been tested with a Keysight B1506A device analyzer. The problems encountered have been analyzed and corrected.Then the design of a high current switching test bench for dynamic characterization is explained. The full-bridge configuration allows controlled and spontaneous commutations so the bench can measure hard and soft switching. The voltage can be up to 10 kV and the current up to 3 kA during the commutation. The choice of the probes is justified. The issues of bandwidth, input impedance and common mode current are taken into account. Data are processed in order to interpolate the switching loss in hard and soft switching.

When you need to design a DC/DC converter

TI is always on a different level....

Common mistakes in dc-dc converters and how to fix them. This is a very good slideshow from Texas Instruments on common issues you’ll come across in power supplies. Whether you’re a beginner or seasoned professional these pointers have some really good advice we see all the time in power switching converters (buck, boost, buck-boost, etc.). These design decisions are highly impactful on PCB layout as well. #pcbdesign #electronics
