Switch-Mode Power Supply (SMPS) Emissions Filtering: Attenuation vs. Leakage Trade-Off

Posted on

Designing a power system for medical devices not only requires meeting the electrical requirements for the system, but also requires understanding the relationship between the attenuation of electromagnetic interference (EMI) and the reduction of leakage currents. The power supply is typically one of the main sources for both EMI and leakage current within a medical […]

Innovative Baseplate Cooling Design

Posted on

The power density of AC/DC converter modules is increasing, but often requires high airflow rates to achieve their stated performance. However, forced cooling using mechanical fans brings reliability, noise and dust pollution issues. Baseplate cooling solves all of these problems, but only if the converter is specially designed from the outset to utilize conducted cooling […]

Are Delivery Robots the Future of Home Delivery?

Posted on

Recently, U.S. regulators have granted permission for certain autonomous vehicle companies to start deploying low-speed electric delivery vehicles, also known as Delivery Robots or BOTs. In today’s current environment, there is a clear appeal to less human-involved food and package delivery – with an estimate that food and grocery delivery revenue is set to grow steadily […]

Tips to Keep in Mind When Selecting an AC-DC Open-frame Power Supply

Posted on

While choosing an open-frame supply, you may need to figure out the ambient temperature of the surrounding area of the power supply, meaning the temperature inside the end application. The heat dissipation solution has the direct influence on the power supply lifetime and output power. The higher the temperature is, the lower the output power […]

How to Connect Batteries in Series and Parallel

Posted on

Series, Series-Parallel and Parallel is the act of connecting two batteries together. By connecting two or more batteries in either series, series-parallel or parallel, you can increase the voltage or amp-hour capacity, or both to allow for higher voltage applications or power hungry applications. Power Sonic explains these connection types below. Click here to learn […]
