Often the success of an EMC test is closely related to the DCDC power supply on boards. This seminar will show the influence of different PCB layout on DC/DC converter EMI signature and impact of passive components to EMC using a real measured DCDC converter. In addition, suitable filter strategies will be presented in order to comply with the limits of CISPR32 Class B from 150kHz to 1GHz.
This presentation was part of Würth Elektronik virtual conference (25-28 Oct.): WE meet @ EMC Digital Days 2021.
