Understanding the EV Powertrain - Power Electronics News
Apr 13, 2023 · A typical EV powertrain consists of a battery pack, inverters for power transfer and electric motor(s) through a final reduction drive. For hybrid vehicles and plug-in hybrid vehicles, there are additional components in the powertrain, like an ICE, dedicated transmission and exhaust system.
Switch Mode Power Supplies – A Brief History
Sep 16, 2024 · The evolution from linear power regulation to switch mode power supply (SMPS) has been transformative for the power electronics industry. Decades of breakthrough research and development combined with continuous improvements across technologies ranging from power devices, controller ICs, and topologies to semiconductor processes and materials have …
Comparing N-Channel and P-Channel MOSFETs: Which is best for …
May 28, 2024 · To achieve a similar on-state resistance R DS(on) as n-channel MOSFETs, p-channel MOSFETs require a two to three-times larger die size. As a result, in more high-current applications, where low conduction losses are critical, the large die p-channel MOSFETs with very low R DS(on) are not the optimal choice.. While the p-channel device’s larger chip size offers …
Silicon Carbide (SiC): 10 Things to Know - Power Electronics News
Mar 17, 2021 · 3. Why SiC overcomes Si in power applications? Despite being the most widely used semiconductor in electronics, silicon is beginning to show some limitations, especially in high-power applications.
SiC Technology: Challenges and Future Perspectives
Oct 12, 2021 · 5G . SiC allows power devices to operate at much higher temperatures, voltages, and switching frequencies, making power electronic modules significantly more powerful and energy-efficient than those made with conventional semiconductors such as silicon.
Boost Converter: Design, Circuit, Equations & More - Power …
Apr 20, 2018 · Boost Converter Design. In most any power supply schematic, the inputs are on the left and power flow is towards the load on the right. A boost is a little more than a backwards buck, though, so for a moment, let’s imagine that V-in and V-out in this schematic were reversed.
Overview of Motor Control in Electric Vehicles
Apr 20, 2023 · Global demand for electric vehicles (EVs) has grown significantly recently. The reasons that have led to the progressive spread of electric vehicles are linked to the joint decision by government institutions and car manufacturers to convert the production of internal combustion vehicles into electric and hybrid vehicles within a few years.
Taiwan’s Ambitious GaN-on-QST Innovation Project Poised to ...
Feb 21, 2024 · Utilizing GaN-on-QST wafers’ intrinsic thermal matching qualities is a key component of the project’s approach, which aims to increase component voltage capabilities from 650 V to 1,200 V. Shen noted the importance of collaboration with research institutes, system integrators and universities to accelerate the adoption of 1,200-V–class GaN-based power …
Intel’s Advancements in GaN-on-Silicon Technology for Efficient …
Feb 5, 2024 · Copper interconnects. As Han Wui noted, most GaN transistors that are today commercially available in the industry employ either aluminum or gold interconnects in the back end. Because both aluminum and gold have worse thermal and electrical conductivity than copper, employing copper interconnects for GaN transistors offers advantages in both heat …
