IGBTs carry Schottky diodes to boost switching efficiency
Infineon Technologies AG has launched a 650 V CoolSiC Hybrid IGBT portfolio in a discrete package with 650 V blocking voltage. The CoolSiC hybrid product family combines the key benefits of the 650 V TRENCHSTOP 5 IGBT technology and the unipolar structure of co-packed Schottky barrier CoolSiC diodes. With superior switching frequencies and reduced switching […]
What is a “Joule Thief” dc/dc converter?
In some applications, it can be useful to drain almost all of the energy of a single cell battery, well below the voltage where the battery is usually considered fully discharged or “dead.” That’s when a Joule Thief dc/dc converter can be attractive. The name implies that the dc/dc converter is stealing Joules of energy […]
