A New Approach to Circuit Breaker Design Using Silicon Carbide Switches - Nov 21
Mechanical circuit breakers can be low cost with minimal losses, but they operate slowly and wear out. Solid state versions overcome the problems and are becoming increasing viable as replacements at...

Modules target low power motor drives in white goods
Integrated and compact the IPMs can be used in fans, pumps, air purifiers and refrigerator compressor drives. The µIPM-DIP family is available in a 12 x 29mm SOP/DIP. There are 32 devices with rugged, high-voltage FredFET MOSFETs specifically optimised for variable frequency drives with voltage ratings of 250 or 500V. The devices are paired with the company’s high-voltage driver IC tuned to achieve optimal balance between EMI and switching losses. They offer DC current ratings up to 4.6A to drive motors up to 150W without a heatsink and are available in both through-hole and surface mount package options. The modules have been added to the company’s iMOTION design platform which integrates digital, analogue and power technologies in a mixed signal chipset to simplify energy-efficient, cost-effective, motor control designs.
