calibre-9.17-release-brings-faster-ebook-conversions

Calibre 9.17 has been released with faster ebook conversion speeds and JPEG XL image support. The open-source ebook editor improves output compression speeds for MOBI, AZW3 and PDB files, which makes conversions to those formats quicker. Converting EPUB to MOBI is what I use Calibre for to read on myContinue Reading

matrix-gains-ground-in-europe’s-public-sector-—-but-replacing-teams-is-another-matter

Matrix-based messaging tools are gaining traction among European governments that seek to gain greater control over sensitive communications data and lessen their reliance on US technology suppliers. The growing interest reflects a broader push toward open-source applications in Europe amid geopolitical uncertainty. Yet the costs and complexity of replacing establishedContinue Reading

hillcrest-says-its-zvs-inverter-cuts-motor-voltage-overshoot-by-more-than-90%

Power conversion developer Hillcrest Energy Technologies has announced peer-reviewed test results comparing its zero-voltage-switching (ZVS) inverter technology with a conventional hard-switched silicon carbide (SiC) inverter. Hillcrest says that in side-by-side testing, ZVS reduced motor-terminal voltage overshoot by more than 90%, from 50% above the DC-link voltage to 4% above it.Continue Reading

using-pxi-based-fault-insertion-and-sensor-simulation-to-test-ev-electronics

Sponsored by Pickering Interfaces. EV battery management and braking systems need to respond safely when sensors fail or electrical faults occur. PXI-based fault insertion and sensor simulation let engineers recreate those conditions under software control, reducing manual patching and making electronic control unit (ECU) tests faster and easier to reproduce.Continue Reading
