Power Electronics

With the ever-increasing need for heat dissipation, high-performance thermal interface materials with higher thermal conductivity and other properties are becoming essential. Driven by this trend, a number of high-performance TIMs are emerging. This article primarily introduces the advantages and drawbacks of advanced carbon-based TIMs. However, it is worth noting that many other TIMs offer superior performance.

Efficiency is the key goal of electric vehicle development. This is especially true of power electronics, where one increasingly adopted approach is to integrate multiple functions into the same package. For automotive OEMs, this can result in reductions in overall weight to increase the efficiency of the vehicle while also reducing the cost of production.

Thermal interface materials (TIMs) are composed of thermal fillers and matrix materials. Thermal fillers are highly thermally conductive substances, while matrix materials are typically used to enhance mechanical properties.

Thursday 11 July 2024 - SiC, GaN, and the Evolution of Power Electronics. In this webinar, IDTechEx will summarize the current market landscape concerning the wide bandgap semiconductors SiC and GaN and other EV power electronics market trends.

With the trend from Si IGBT to SiC MOSFET in electric vehicle (EV) power electronics, the junction temperature is expected to increase from 150°C to 175°C with the potential to exceed 200°C. This brings significant challenges for thermal management.

In 2008, the commercialization of the silicon carbide (SiC) MOSFET marked a major turning point for the power semiconductor market, representing its first significant development in decades. This technology was pioneered in electric vehicles (EVs) with the 2017 Tesla Model 3. The SiC MOSFET is a transistor that promises high power density, greater efficiency, and is less fallible to high temperatures.

IDTechEx Research, a trusted provider of independent market intelligence, announces the availability of a new global Thermal Management for EV Power Electronics market report, "Thermal Management for EV Power Electronics 2024-2034: Forecasts, Technologies, Markets, and Trends".

Ensuring that sensitive electronic components are not adversely affected by radiated electromagnetic interference (EMI) is an essential part of circuit design. Where compactness and close component proximity are a priority, such as in smartphones and smartwatches, conventional board-level shielding with metallic enclosures is increasingly being replaced with conformal package-level shielding.

Using graphene to improve the performance of energy storage devices has been a key focus ever since the 2D material was isolated. As soon as the first commercial graphene manufacturers were established, there has been a steady stream of announcements related to batteries, but perhaps none are as significant as the 2023 news of Evonik entering the field with their investment in SuperC.

Thursday 23 February 2023 - Opportunities for Integrated Functionality. In this webinar Dr Matthew Dyson, a Principal Technology Analyst at IDTechEx, will discuss the following topics: - The status of IME and competing approaches for creating functional and decorative interfaces across multiple application sectors. - The challenges and benefits associated with functionality integration, and how the value proposition of IME is likely to grow over time. - IME specific material requirements, especially for conductive inks. - A roadmap for IME adoption, segmented by industry.
