Integrated power modules offered in alternative DIP packaging

Integrated power modules offered in alternative DIP packaging
Surface mount devices are not the answer for every customer and International Rectifier recognised this issue and launched the µIPM-DIP family of highly integrated, compact Integrated Power Modules (IPM). The devices were originally launched, and are still available in a compact, surface mount package.

Half-bridge power module enables 99% efficiency

Half-bridge power module enables 99% efficiency
Packaged in industry-standard 62mm housing, the CAS300M12BM2 300A, 1.2kV half-bridge module has been introduced by Cree. This silicon-carbide (SiC) module reduces energy loss due to switching by more than five times compared to the equivalent silicon solution, according to Cree. The company has also claimed that this best-in-class efficiency enables for the first time all-SiC high power converters rated up to the megawatt level.

ASIC-based current transducers extend range to 250A

ASIC-based current transducers extend range to 250A
PCIM 2014: Three HO series open-loop, Hall-effect ASIC-based current transducers have been released by LEM. They have a wide operating range of -40 to +105̊C. Stéphane Rollier says that the transducers are the only ones in the industry to offer over-current protection. The versatile devices offer a range of mounting options, PCB, panel or bus bar, and exploiting the aperture which measures 15 x 8mm, for cables and clamps.

FET technology reduces EMI and boosts efficiency

FET technology reduces EMI and boosts efficiency
PCIM 2014: Targeting small motors, i.e. under 100W, the integrated FSB70xxx modules deliver up to 44% better light-load efficiency, compared with the leading competitive device, claims Fairchild Semiconductor. The level of integration and inclusion of the company’s FRFET (Fast Recovery Field Effect Transistor) also increases thermal efficiency to 12%, due to the improved junction to case formation.
