Are You Wasting Money, Space and Efficiency By Overdesign? Hybrid and electric vehicles, medical, and aerospace applications are driving more thermally tolerant, higher efficiency and more compact SiC switching topologies. Register to learn fundamental SiC design considerations beyond what’s typically shown on datasheets. Key takeaways: Understand how SiC design considerations including avalanche capability,
If the goal of moving to electric vehicles (EVs) is to reduce harm to the environment, then getting people out of individual cars and on electrified public transit should be a premier destination as well. While they may not look as sleek as the latest Tesla, electric buses are going places, too, despite similar range
GaN High Electron Mobility Transistors (GaN HEMT) have lower driving loss and shorter deadtime circuit benefits due to significantly reduced gate charge (Qg) and output capacitance (Coss) compared to Silicon MOSFETS. Therefore, GaN HEMTs show significant advantages over Silicon MOSFETs in high-frequency soft-switching resonant topologies such as an LLC resonant converter. With increased switching frequency
Part of the Thermal Engineering Webinar Series from ATS While the physical design of a chassis becomes standardized, the power dissipation inside of that chassis is anything but standardized, which can put a strain on the enclosure’s cooling capacity. Engineers have to ask several questions, such as what cooling technology can they use for
Now available on-demand! Hosted by Power Systems Design, featuring Cree, Power Integrations and Analog Devices Now wide bandgap materials are established in the marketplace and being deployed in many applications, manufacturers are looking for ways to differentiate their products from the competition. Packaging, integration and higher voltage capabilities are just some of the
The demand for silicon carbide (SiC) MOSFETs and diodes is growing rapidly, particularly within automotive, industrial, and energy applications due to the improved efficiency, superior power density, and lower system costs. Learn how to approach your design correctly, make all the right considerations and select the optimum SiC MOSFET for your system from the
For EVs, the semiconductors used in traction inverters have a significant impact on efficiency, power density, and cooling requirements. The three-phase AC motors used in today’s EVs run at voltages up to 1,000V and switching frequencies up to 20 kHz. This is very close to the operational limits of the silicon-based metal-oxide semiconductor field-effect
Selecting an appropriate EMI filter is critical to achieving optimum size, performance, and cost. Different types of EMI filters provide different levels of suppression and have different characteristics. What works for one system might not work well in another. For this reason, it is essential to understand the considerations when selecting an EMI filter.
With silicon nearing its physical limits, electronics manufacturers are turning to non-traditional semiconducting materials, notably wide-bandgap (WBG) semiconductors. Some are adopting these technologies to hit cost and performance targets that otherwise can’t be reached, and while others seek to differentiate their products from their competitors’.

By switching to SiC MOSFETs, power system designers can significantly boost power density, lower switching losses, and improve thermal management in OBCs for electric vehicles. Power systems in electric vehicles (EVs), on-board and off-board battery chargers, and other energy storage systems are demanding greater energy efficiency to pack more power into... Read More!
