There are many applications of fire that are productive and warming. Fire can be a real risk if the components on pcb has not been selected correctly for high voltages. In some circumstances, incorrectly selected components can create Transient voltage, which could cause damage to the board and even leads to spark fire. To achieve electric shock protection , electronic equipment must have an effective insulation method ,which can be divided in to clearnce and creepage distance and solid insulation materials.

Do you recognize the difficulty to make a proper PCB layout so you get the most out of your SMA connector? A good SMA connector does not mean that you do not face any reflections in the transport in HF signals. There are a lot of factors you need to take care of to get the most of the connector. In this session we want to give more insight which parameters can make it that the losses/reflection are low or high. We are going more in depth into the PCB layout. And what would be impact of (small) changes on your signal integrity. WE set-up some different layout with the outcome of the changes with S11 and S21 parameters. After this session you have more insight what the impact could be of small changes in your PCB layout around a SMA connector. So if you want to dive into the world of HF signals and PCB layout sign in quick.

The LoRaWAN protocol is a Low Power Wide Area (LPWA) networking protocol designed to wirelessly connect battery powered IoT devices to the internet. LoRaWAN targets key Internet of Things (IoT) requirements such as bi-directional communication, Long Range coverage, end-to-end security, and Low power consumption.
LoRaWAN networks are typically laid out in a star topology in which gateways collects the data from nodes and transmits this data to central Network Server (IoT platform).
LoRaWAN IoT devices operates in ISM (Industrial, Scientific and Medical) licence free frequency band. LoRaWAN is flexible for rural or indoor use cases in smart agriculture, smart cities, industrial IoT (IIoT), smart environment, smart homes and buildings, smart utilities and metering, and smart supply chain and logistics.

REDEXPERT Filter Designer is suited for input filters for DC-DC converters, AC-DC converters, but also output filters. The tool is very useful to design a differential mode input filter or specific noise filter without going into complex filter calculation. Instead of using trial-and-error for determining the components needed to create the filter, the REDEXPERT EMI Filter Designer does all the calculations based on a few input parameters. It uses the non-ideal component models, which includes the parasitics, to determine the performance of the filter and also takes into account system impedances. Using the correct input parameters, as described, the tool can reduce the process of making a design EMC compliant in time and cost.
Speaker: Christoph Birner - Duration: ca. 45 min incl. Q&A

In this webinar, I will highlight what we can do to keep the emissions low. I will discuss which properties of the transformer impact the EMC and I will show what techniques we can implement in the construction of the transformer to minimise this impact. I will show examples of good and bad design practices, ranging from flying leads to shield windings.

Speaker: Óscar Ciordia, KDPOF - Duration: ca. 45 min incl. Q&A
Modern automobiles integrate numerous functionalities that require high-speed links for their proper functioning, for example, cameras, radars, displays, sensors, etc. Current solutions based on copper cables do not successfully satisfy automotive requirements at a reasonable cost. However, with the incorporation of fibre optics, KDPOF makes possible optical multi-gigabit links for harsh environments at a low cost. The technology makes these links much more efficient while providing greater reliability and low-cost implementation.

Dew point detection is vital for protecting humans and machines. The dew point is an essential environmental parameter that signifies the temperature at which air reaches saturation, resulting in condensation. This condensation can have detrimental effects, such as causing damage to delicate equipment, creating hazardous conditions, and posing risks to human health and safety. MEMS (Micro-Electro-Mechanical Systems) humidity sensors offer compact and reliable monitoring, enabling real-time dew point detection. Continuous monitoring mitigates risks to equipment, hazardous conditions, and human health, ensuring safety and optimal performance.

Speaker: Simon Mark - Duration: ca. 45 min incl. Q&A
When designing a complete solution of SPE, a structured approach is extremely important. This can ensure space, weight and cost reductions of over 50%.This presentation will demonstrate the approach to designing an interface for Single Pair Ethernet with and without Power over Single Pair and explain the necessary steps. The first thing to consider when designing is whether Power over Single Pair is desired. If a pure data transmission is planned, an extremely compact design can be created. However, if additional power transmission via SPE is to be present, other components must be used. This is because using the passive components that are also used for SPE without power transmission would result in a weight and cost increase by a factor of two. By an intelligent choice of the filter components, an optimal circuit can be designed for a single pair Ethernet interface without or with additional power transmission, which meets all the required criteria.
After the presentation, the circuit designer is able to independently create the optimal solution for him using simple steps.

GaN brings benefits in power conversion thanks to lower parasitic capacitances which allow to reduce the losses and increase the operating switching frequency. Depending on the topology, GaN technology can be used to obtain higher efficiency or to increase the power density, this reducing the size of the application. QR flyback with GaN switch gains both in efficiency and in power density, with respect to a similar solution with silicon. Additionally, a comparison between QR flyback with GaN and active clamp flyback with GaN will be shown.

To sell a radio product into the market it is necessary to fulfill all national requirements. Beside the common aspects of EMC, safety and health for a radio device the radio spectrum matters to guarantee an efficient use of its limited resource. Although these aspects are already considered on level of the Würth Elektronik eiSos radio modules it is important that the manufacturers of the end devices engage with this topic, as they are fully responsible. This presentation gives an insight in requirements for the radio spectrum and protocol.

Conducted emission measurements help to understand the power converter performance which can be improved by EMI input filters. In order to reduce conducted emissions significantly it is important to understand the total noise spectrum incl. the separation into common mode and differential mode. While running multiple FFT correlated with the time domain an oscilloscope like the R&S®RTO06 captures the noise results which enable optimized EMI input filters. Practical measurement examples demonstrate the iterative filter design process.
