Using a Rogowski coil [3] followed by integrator and comparators is an alternative way to control a high-frequency resonant converter SR. Figure 4 is a block diagram illustrating SR control with a ...

One of the joys of writing for Hackaday comes in learning new things which even after a long engineering background haven’t yet come your way. So it is with the Rogowski coil, an AC current s… ...

A Rogowski coil is a device for measuring AC current that differs from a conventional current transformer in that it has no need to encircle the conductor whose current it measures. They’re by ...

The name of this sensor stems from its figure-of-eight shape (∞ sensor) and very high bandwidth (1 GHz upwards). It is a magnetic field sensor, and can be thought of as a planar subset of a Rogowski ...

Newly released is the first AC current sensors family based on patent-pending Perfect Loop Technology. After calibration, the new RT series achieves absolute accuracy of better than 0.65 percent ...

When developing the new Rogowski coils, LEM decided to offer a simple and generic product, keeping in mind that the integrator technology leads to the best performances and is a well known method.

The new wide-band screened CWT MiniHF probe eliminates the extra bulk and bandwidth restrictions imposed by conventional screening techniques, while delivering the known advantages of a Rogowski coil.
