Design considerations for EMI, EMC immunity and isolation requirements in industrial drives

This training outlines the system requirements for EMC immunity, EMI and isolation when designing a variable speed drive. A brief overview is given on the corresponding IEC standards with the test requirements and pass criterion. Subsystem hardware design examples are shown leveraging TI reference designs for an interface to absolute digital encoders and dual port Gigabit Ethernet to pass EMC immunity and EMI, and a 3-phase inverter with reinforced isolated IGBT gate drivers to meet isolation and common mode transient immunity. For each, the system test requirements will be translated to corresponding IC datasheet parameters. Tips and tricks throughout the presentation help to select the optimum ICs.

What you’ll learn:
• Overview on IEC standard requirements and pass criterion for variable speed drives.
• How semiconductor/component level standards enable systems to pass system IEC standards.
• Design industrial IEC compliant hardware.
• See how TI reference designs are done to pass IEC standards.

1. Why EMI/EMC and isolation standards for Industrial Drives

EMI/EMC and isolation standards for motor drives provide surge, EFT, ESD and EMI protection for longer lifespan and higher reliability of your application. Watch this to understand the different standards from the system level—down to the component level.
