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

    Leave a Comment

    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 device. TT Electronics’ Engineering Manager Dylan Howes discusses the relationship between EMI and leakage currents within the power supply, some methods for reducing both without impacting the other, and how choosing the right power supply can save time and money.

  2. Innovative Baseplate Cooling Design

    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 measures, such as the new RACM230-G and RACM550-G series from RECOM, which delivers high power in a small form-factor along with a long list of other useful features.

  3. Are Delivery Robots the Future of Home Delivery?

    Leave a Comment

    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 and reach $200 billion by 2025. Autonomous delivery vehicles enable a future where everything comes to you directly on-demand. Prior to the COVID-19 pandemic small sidewalk robots were gaining traction. In general these sidewalk robots move slowly are light-weight and do not present a risk to pedestrians.
