One of the primary purposes of a gate driver is to enable power switches to turn on and off faster, improving rise and fall times. Faster switching enables higher efficiency and higher power density, reducing losses in the power stage associated with high slew rates. However, as slew rates increase, so do measurement and characterization uncertainty.
Effective measurement and characterization considerations must account for: ► Proper gate driver design – Accurate timing (propagation delay in regard to skew, PWD, jitter) – Controllable gate rise and fall times – Robustness against noise sources (input glitches and CMTI) ► Minimized noise coupling ► Minimized parasitic inductance
The trend for silicon based power designs over wide bandgap power designs makes measurement and characterization a greater challenge. High slew rates in SiC and GaN devices present designers with hazards such as large overshoots and ringing, and potentially large unwanted voltage transients that can cause spurious switching of the MOSFETs.
5G introduces test challenges related to massive MIMO, mmWave frequencies, and over-the-air (OTA) test. Successfully overcoming these challenges is the only way to reach 5G commercialization before the competition.

Get an introduction to modeling thermal performance of high-voltage cables in COMSOL Multiphysics® in this webinar. High-voltage power cables are major assets and are expected to work reliably for many years. One of the factors affecting reliability is thermal performance of the cables. This has to be determined at the early stage of the design and is achieved by calculations of the thermal rating (often called ampacity).
Ampacity calculations usually involve two different physics: heat transfer (in solids and gases/liquids) and electromagnetics (Joule losses in the conductor, dielectric losses, and electromagnetic induction). Some models of cable installations are relatively easy to solve, while others require in-depth knowledge of the physics and experience in building FEM models. For example, the heat transfer from directly buried cables involves only conduction, while for cables installed in air, radiation and convection must be taken into consideration.
This webinar will demonstrate how to build finite element models of underground cables using COMSOL Multiphysics®. The presentation concludes with a Q&A session.

Testing state-of-the-art radar warning equipment with adequate RF and microwave signals is a challenging task for radar engineers. Generating test signals in a lab that are similar to a real-life RF environment is considered a supreme discipline when evaluating advanced radars. A scenario for testing radar-warning receivers (RWR) can easily contain many highly mobile emitters that are capable of mode changes, many interfering signals, and a moving multi-channel receiver. Today, there are intuitive and easy-to-use software tools available that take a lot of work off the hands of radar engineers.
In this seminar, you will learn how to:
Create radar scenarios ranging from simple pulses to the most demanding emitter scenarios using PC software
Generate complex radar signals with off-the-shelf vector signal generators

Learn about the importance of using a range of methods in the 3D electromagnetic (EM) simulation of installed antenna performance.
3D EM fullwave simulation is a common practice for antenna designers and Analyst. The variety in antenna topologies and design specifications necessitate a range of simulation algorithms to ensure an efficient or even feasible solution is available.
This range of technology becomes even more important as antennas’ operation in the installed environment is considered. The application of different EM methods as well as hybridization is discussed via an example workflow of antennas installed on an aircraft. Techniques for specific installed antenna scenarios including radome analysis, co-site interference and initial field of view analysis are presented using the SIMULIA CST Studio Suite toolset.
