Watt & Well set its RF (radio frequency) cage into the engineering lab. A three-day installation to create a place that shields anyone and anything inside, from magnetic fields, electrical fields, plane waves, and microwaves. A cutting-edge cage for ambitious prospects.

 

Approaching the electromagnetic principle

First, don't let the cage-like look fool you. The opportunities it gives are tremendous. Some politicians use it, for instance, to discuss sensitive matters without having the doubt of being spied on with sophisticated technology. Also, sometimes, when you commute by air from place to place, you enter a shielded room without knowing it! Indeed, the plane has an outer shell of aluminum hull to prevent lightning harm, making it a perfect example of how in daily life, this application is used. To unfold all the applications possible, it is necessary to understand the principle of the cage.

 

Applied to power electronics, the principle of an EMC cage is simple. It aims at canceling out electric charges within the cage's interior. This neutral environment allows reproducible measurements of the power electronics equipment to enhance its electromagnetic compatibility once integrated into a system. When running tests, this practice prevents from electromagnetic interferences (EMI), caused by mobile phones for example or any powered device.

 

Extending in-house capabilities with an EMC cage acquisition

Originally initiated for the emobility customers, the EMC cage investment ensures the compliance of the onboard EV charger prototypes, with numerous standards including CEI 61000-4 series. A noteworthy point as Watt & Well gives high priority to respond well to normative requirements (DO160 for aeronautics, ECSS for space product).

This extended in-house capability is a positive sign of the commitment towards the ever-increasing need for quick adjustments and a better understanding of the system behavior at short notice. The engineering team shall fasten iteration during the pre-qualification and qualification phase. Thus, provide rapid results to customers with tight-deadline projects.

More importantly, Watt & Well is definitely deepening its expertise regarding electromagnetism compatibility with engineering training on the subject and partnerships with laboratories specializing in environmental testing.
