DC applications on the grid: solving flexibility
In the late 1880s, Thomas Edison and Nikola Tesla began a conflict known as the war of the currents. The two inventors and industrialists battled over whether Direct Current (DC) or Alternating Current (AC) should be used to distribute electricity. Ultimately, AC’s ability to work with transformers to easily increase and reduce voltage to transmit electricity across long distances won, and has reigned supreme for more than 100 years.
Selecting power inductors with TDK
When the power supply voltage is decreased, voltage fluctuations can become more dangerous, requiring a high-performance DC/DC converter in order to operate within safe parameters. DC/DC converters can help to address these requirements, and power inductors are crucial components that affect DC/DC converters’ performance thereby enabling speed increases in LSIs while significantly reducing power requirements.
New 650V CoolSiC hybrid IGBT discrete brings efficiency
Infineon Technologies has launched a 650V CoolSiC Hybrid IGBT portfolio in a discrete package with 650V blocking voltage. The CoolSiC hybrid product family combines key benefits of the 650V TRENCHSTOP 5 IGBT technology and the unipolar structure of co-packed Schottky barrier CoolSiC diodes.
Four terminal current sense resistors offer high accuracy
Current sensing for high efficiency can be done easily and economically using current sense resistors. As resistance values are reduced, the measurement error due to lead resistance becomes more of a problem. For applications desiring high efficiency with the best possible temperature accuracy, four terminal current sensing products are a good choice.
Mixed signal testing using modular PC instruments
Testing mixed signal devices requires both analogue and digital measurements. Analogue measurements, which acquire data samples with high amplitude resolution as a function of time, are used to test physical layer compliance with test standards, and digital measurements, which obtain data samples with single bit resolution versus time, assure data state as a function of time and permit evaluation of protocol content.Oliver Rovini - Technical Dire...
Power supply architectures for isolated gate drivers
Many power electronic applications such as automotive traction drives, PV inverter, railway traction drives and servo drives require a three-phase inverter power stage to convert DC to three phase AC voltage. Gate drivers are needed to drive the semiconductor devices. Vikneswaran Thayumanasamy and Kevin Lenz look at topology options
