In part 9 of our 10-part series on designing a power supply, we’re focusing on EMI and RFI testing. This stage is often overlooked due to difficulty and cost. However, ignoring this step can lead to unpleasant surprises and delays as your deadline looms. We also strongly recommend testing for EMC issues early in the design process to avoid unnecessary board turns and missed timelines.
So, grab your spectrum analyzer and your pre-defined EMI compliance mask and catch those pesky EMI problems before you arrive at the test house later on.
