Schurter DKIH-EVB Evaluation Boards for Current-Compensated High-Current Chokes

• Development tool for 1- and 3-phase systems
• Suitable for DKIH-1 and DKIH-3
• For high power applications

Schurter is now offering proven test circuit boards for the DKIH-1 and DKIH-3 high-current chokes. With these, an EMI filter circuit for 1- or 3-phase systems can be set up and tested easily and quickly in an iterative process without having to make any adjustments to the layout of your own PCB.

Every developer of an electrical or electronic device is faced with the same problem: In the end, the device must comply with international EMC guidelines regarding emission and immission. Problems, often of an unpredictable nature, mostly arise in the power section. Like most electronic assemblies, the power section is increasingly being mounted on printed circuit boards using discrete components. A compact filter directly on the printed circuit board with discrete components is therefore usually the best solution. And a current-compensated choke with capacitors is the most efficient measure for EMC suppression.

DKIH-EVB
With the new SCHURTER DKIH-EVB (Evaluation Board) test circuit boards, a wide variety of filter configurations can be quickly calibrated with the DKIH series of current-compensated chokes without making any changes to an existing PCB layout. With high L and C values, the vast majority of disturbances can be adequately attenuated. The art of filter design, however, lies in finding an effective and at the same time cost-optimized combination of components. Often, slightly smaller L and C values are sufficient if these are perfectly combined. An EMC measurement of the finished system or device is indispensable for the declaration of conformity.
