In the previous article of this series, we looked at some of the major noise considerations in different power regulator topologies. Noise from these sources eventually makes its way to other components, and it could interfere with other portions of a system. Depending on the types of components used elsewhere in the system, noise may be innocuous or it may cause a design to … [Read more...]
EMC Design in Power Electronics Part 1: Regulators
INTRODUCTION Modern electronics demand low EMI and EMC conformance, both of which are related to component selection and physical layout in the power supply section of a device. Many more designs are demanding higher power levels alongside high power efficiency, as well as low-noise power supplied to mixed-signal systems. As a result, EMI and EMC challenges are more apparent … [Read more...]
When EMC is of Vital Importance
Santa Rosa, California, March 2023 – Electromagnetic compatibility (EMC) is a growing concern in medical technology and regulatory standards continue to implement measures to prevent disruption in wireless communication between medical applications, which can have severe consequences for the patient. SCHURTER works diligently to stay abreast of equipment trends and their … [Read more...]

EMC Focus: Power Supplies
Electromagnetic Interference (EMI) is always a potential problem with switched-mode power supplies, both AC-DC and DC-DC converters. Modern designs can perform well for emissions and immunity but external connections must still be correct for the best performance. Sometimes, extra filtering is necessary to meet specific application requirements. However, incorrect filter … [Read more...]
EMI Filtering 101: Understanding the Basics
Introduction To start at the very beginning, what is an electrical filter? An electrical filter can be passive, active, analog, or digital. It is a device usually composed of discrete components which can be placed between circuits, networks, or equipment/systems to either emphasize, de-emphasize or control the frequency components of a desired or undesired signal. The term … [Read more...]

Santa Rosa, California, February 8, 2023 – In times of climate change, there is increasing awareness for the topic of sustainability. But little will be achieved without action. SCHURTER intends to take a new path in this direction and believes its prospects for progress to be excellent. Founded in 1933, the company operates successfully with components for safe energy supply, … [Read more...]
5 Steps to Selecting the Right RF Power Amplifier
Introduction You need an RF power amplifier. You have measured the power of your signal and it is not enough. You may even have decided on a power level in Watts that you think will meet your needs. Are you ready to shop for an amplifier of that wattage? With so many variations in price, size, and efficiency for amplifiers that are all rated at the same number of Watts, many … [Read more...]
Good SI, PI and EMC require this most of all…
Good SI, PI and EMC require a proper, grown-up understanding of electricity... Instead of what circuit designers are taught! As electronic designers, we were taught the children’s version of electricity at school, college, university, etc. This is the version that pretends (just as the SPICE simulator does) that electricity flows as little packets of charge totally inside … [Read more...]
