High-: 1μG = 0.1nT, 1mG = 100nT, 1G = 100μT, 10G = 1mT, 10,000G = 1T deg (B) and (H): () medium-B=μoH. μ o = 4pi x 10-7 H/m SI, B, H A /m A/m. therefore, medium-, = 796kA/m. c μ o = 1, B high-, H 1 high- = 1

Danisense DCCT Ultra-Precision DC Current Sensors: How They Work

A fluxgate works by using an excited coil of soft magnetic material as the probe; saturation/desaturation cycling and signal processing let the coil measure the magnetic field proportionally. This opens up several current-sensor designs: it can simply replace an air-gap Hall probe, and the coil can take a split form.

Danisense Fluxgate Current Sensors: Technology and Principles

The Danisense fluxgate is a proprietary closed-loop compensation technique with a fixed excitation frequency and second-harmonic zero-flux detection. The field produced by the primary current in the ring core is cancelled by a compensating secondary current from the integrator: the fluxgate senses the sub-ppm field from DC to below 100 Hz and instructs the integrator to compensate, while at higher frequencies the feedback winding detects the field and again corrects it.

Micsig Optically Isolated Probes for SiC and GaN: MOIP1000P, MOIP500P, MOIP200P

SiC and GaN devices combine high breakdown voltage, low on-resistance and small parasitics. In switch-mode power supplies they cut losses, allow higher switching frequency and improve efficiency, power density and reliability. Optically isolated probes reproduce the VGS drive waveform with high fidelity.
