9 AM: GaN/SiC Challenges for Passive EMC and Power Components

Speaker: Andreas Nadler | Duration: ca. 45 min incl. Q&A

Especially in power ranges above 1kW, WBG semiconductors are becoming more and more popular due to their efficiency. However, the developer also faces new challenges. This webinar will help the developer to understand what is important when selecting passive components for auxiliary power supplies for e.g. SiC-FET. In addition, the most important EMC stumbling blocks in this area will be explained.

10 AM: Better Safe than Sorry; Practical EMC Design Considerations

Speaker: Mohamed Al-Alami | Duration: ca. 45 min incl. Q&A

It is usually the case that EMC is not considered at the early stages of the design. This session looks into the implementation of good design practice to optimize signal integrity. This includes:
(1) A practical review of filter design and component selection (including parasitics) using LT Spice simulation and REDEXPERT.
(2) Identifying and simulating, using LT Spice, EMI issues as well as solutions. This is based on a Type 2 PoE PD design with a layout and tracking problem.
(3) Investigating different interfaces and presenting relevant filtering, OVP and recommended layout and tracking.

Speaker: Dr. Heinz Zenkner | Duration: ca. 45 min incl. Q&A

The webinar describes what is necessary for the development of a GB Ethernet interface, between Phy and Ethernet connector. It goes into detail about the circuit technology, the components and the layout. Points such as matching of the symmetrical signal paths, protection against transient overvoltage, selection of suitable components, design of the ground system, placement of the components on the PCB and layout design are shown, using a practical example. Finally, the topic of EMC is also taken into account.

1 PM: Secondary-side Compensation for Isolated Power Supplies

Speaker: Carlo Lombardi, Microchip Technology | Duration: ca. 45 min incl. Q&A

In most of the grid connected applications the auxiliary power supply is normally implemented using the flyback topology. To get the required stabilized voltage(s) a voltage compensator is needed, and in the most of the cases it is implemented on the primary side of the flyback converter. In this webinar a solution based on a primary-side start-up IC (MCP1012) in conjunction with a secondary-side controller is presented highlighting the advanced control techniques that may be implemented using a secondary side controller. Finally a real application for led lighting will be presented.

10 AM: Inrush Current for Connectors

Speaker: Alexandre Chaillet | Duration: ca. 45 min incl. Q&A

All connectors are given for a working current. This is the maximum current that can be used for this connector at any time for any duration. This current brings temperature rise through Joule effect. For specific applications (motor starters, capacitance discharge…), it is requested to use higher current than usually accepted by the connector but only for a short time. We propose a solution to answer to this problematic: what value for the current, its duration and how many times it is possible. And thus keeping reasonable temperature rise and full quality and life time of our products. Most of our competitors does not offer this solution.

11 AM: USB-C "From Layout to Production"

Speaker: Fabian Altenbrunn | Duration: ca. 45 min incl. Q&A

USB-C now offers different connector variants from USB 2.0 in a Type-C casing to Type-C for 10 GBit data rates. The housing variants have also become more diverse. From the horizontal hybrid type over vertical variants to the mid-mount type, which is placed in a PCB cutout. All these types have their special characteristics, which in many cases have to be considered already in the layout, so that a problem-free production is possible afterwards. Therefore, we would like to highlight these points and show possibilities how to deal with these issues. Also the printed circuit board itself and its production cannot be left out, since it brings certain restrictions with itself, which should be considered, in order to obtain an optimal result. Once all this has been done, it is then a matter of controlling the manufacturing process in its various steps from stencil printing to the soldering oven and optimizing the parameters so that the filigree type-C connectors can also be processed in a way suitable for series production.

3 PM: High Frequency Common Mode Noise and Solutions

Speaker: Muhammad Ali Khalid | Duration: ca. 45 min incl. Q&A

The USB 3 data handling capability has increased manifolds over the past few years and we can see the same trend with other digital switching circuits like HDMI and Thunderbolt etc. The increased functionality comes with a hidden cost i.e. common mode noise. This noise can interfere with 4G/LTE or Wi-Fi/ Bluetooth antennas resulting in “Antenna de-sense” and communication failure.
In this webinar we present and explain how the high frequency common mode noise is generated and what are the different solutions that can be used as counter measures. An innovative common mode choke design, based on transmission lines model is also presented which can be a game changer for your designs.

1 PM: Meeting Challenging Efficiency Standards with Bridgeless Totem Pole Power Factor Correction

Speaker: Alessandro Maggioni, onsemi | Duration: ca. 45 min incl. Q&A

The input bridge rectifier found in almost all AC-DC power supplies generates losses that present a challenge in achieving the highest possible efficiency. However, removing the diode bridge, PFC FET and boost diode in favor of a totem pole PFC solution enhances efficiency using active switches. The control of such circuits is complex. Often, a microcontroller is needed and associated code which presents a barrier to adoption for design teams where time is limited. Onsemi NCP1680 mixed signal PFC controller is discussed in the article as it provides a code-less solution for totem-pole PFC.

2 PM: Filter Components – Mode of Operation and Selection Criteria

Speaker: Mario Möller | Duration: ca. 45 min incl. Q&A

There is a huge variety of filter components, both for common mode and differential mode disturbances. The variation regarding their internal structure and electrical characteristics is often unclear, leading to easily avoidable reworks of the filter design. In this Session, we will explain the basic construction and mode of operation for ferrite based filter components. Following a live measurement to compare different inner structures, you will learn about the criteria to select the proper components for your application.

3 PM: MagI³C MicroModules with Adaptive Switching – All-in-one Solution for the Industrial Sector

Speaker: Timur Uludag | Duration: ca. 45 min incl. Q&A

Warehouses with multi-faceted conveyor systems provides a prime example of an industrial environment where there are numerous electronic applications and rail voltages. Sensors, actuators and control units are just some examples of the countless applications that are implemented in industrial warehouses. Each of these applications has its own requirements in terms of supply voltage, current and installation volume. All the applications have one thing in common: they have to be realized in a confined space. Tight space, by definition, requires tiny DC/DC converters which have excellent efficiency and thermal performance. This webinar explores the electrical, thermal and EMI needs of these applications and shows solutions to find the best DC/DC converters to overcome these obstacles.

9 AM: EMI Debugging of a Low Power Buck Converter

Speaker: Frank Puhane | Duration: ca. 45 min incl. Q&A

The CE mark is an important seal of quality for electronic components. To obtain this certification, the component must pass the EMC test. EMC testing includes various tests such as conducted and radiated emission and is often a very lengthy process that requires several iterations. To understand the importance of an proper design we show two different layouts and compare the results. Furthermore, we will show the importance of the right components to achieve a stable and efficient design with low emissions.

1 PM: Security in IIoT Applications

Speaker: Adithya Madanahalli & Stefan Messing | Duration: ca. 45 min incl. Q&A

35 % of businesses in a global survey think security is the major concern for any IloT implementation. Complexity in IIoT stems from the fact that the system has multiple elements interacting (devices, cloud, users…) at different levels (physical, embedded, cloud…). A number of regulatory standards are being introduced to provide a common framework to tackle this issue. The ETSI EN 303 645 provides baseline requirements for such a system. In this webinar, we focus on embedded security and present a basis for a secure IIoT solution based on the Calypso Wi-Fi module.
