WEB CONFERENCE: ELECTROMAGNETIC COMPATIBILITY

Towards an EMC compliant design in power electronics

LIVE | 2022-05-24 | 2:00 PM - 4:00 PM CEST

Optimizing the EMC behavior in the design of switching power supplies is a major challenge for the designer. In the web conference, methods and tools for the reduction of electromagnetic noise are presented and discussed.

The reduction of electromagnetic noise in power electronics systems is crucial for fulfilling the EMC requirements and regulations. Therefore, it represents a big challenge in the design of switched mode power supplies.

Reducing noise is not only important to pass various EMI test, but also to get a switched mode power supply circuit to work at all. Thus, the sources of noise as well as the most important ways of how the generated noise can be reduced will be described and discussed.

The strategies for a successful DC-DC-converter design and methods how the hardware designer can optimize the design for EMC performance without changing the semiconductors will be presented. The influence of the switching regulators, of an unfavorable PCB layout as well as of the choice of inappropriate passive components is enormous and will be analyzed and explained in detail.

These are the central topics that were discussed at the web conference on May 24th 2022 at 2 pm:

  • The sources of noise in switch mode power supplies and the most important ways of how the generated noise can be reduced.
  • The PCB board layout, filtering and reducing parasitic inductances as well as using optimized switching regulator ICs as means for the optimization of the EMI behavior.
  • Main EMC tests that can be used to verify the compliance of a DC-DC-converter.
  • Discussions of strategies for a successful DC-DC converter design presented in theory, with LT spice simulations, as well as with measurements.

Part 1 (Analog Devices): EMC Fail with a DCDC design! How can we improve it?

There are two main EMC tests that can be used to verify the compliance of a DCDC converter. In this presentation we will show how the hardware designer can optimize his DCDC design for EMC performance without changing the semiconductors.

The influence of an unfavorable PCB layout as well as the choice of inappropriate passive components is enormous. Using two DCDC switching regulators, this difference will be demonstrated in theory, with LT spice simulations, as well as with measurements. Strategies for a successful DCDC design will be shown.

Part 2 (Würth Elektronik): Reducing Noise in Switch Mode Power Supplies

This presentation will introduce the sources of noise in any switch mode power supply and it will discuss the most important ways of how this generated noise may be reduced. Reducing noise is not only important to pass various EMI regulations, but also to get a switch mode power supply circuit to work at all.

Elements of this presentation are PCB board layout, filtering and reducing parasitic inductances by using optimized switching regulator ICs.
