Overview of Motor Control in Electric Vehicles
2023年4月20日 · 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.
Silicon Carbide (SiC): 10 Things to Know - Power Electronics News
2021年3月17日 · 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.
USB-PD 3.2: Key Updates and Impact - Power Electronics News
2024年5月29日 · USB-PD R3.2 introduces significant changes. While the required current is the same as in R3.1, AVS is now required for Standard Power Range (SPR).
Boost Converter: Design, Circuit, Equations & More - Power …
2018年4月20日 · 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.
SiC Technology: Challenges and Future Perspectives
2021年10月12日 · 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.
Silicon Carbide: The Future Of Electric Vehicles - Power Electronics …
2020年8月3日 · What is Silicon Carbide technology? Silicon Carbide (SiC) is an innovative technology that will replace silicon in many applications. The idea of using SiC for electric vehicles (EVs) was born when efforts were made to increase the efficiency and range of such vehicles, while reducing the weight and cost of the entire vehicle and thus increasing the power density …
Comparing N-Channel and P-Channel MOSFETs: Which is best for …
2024年5月28日 · 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 …
SiC and GaN usage in bidirectional power applications
2023年7月17日 · How to make SiC bidirectional switches. SiC power transistors, either planar MOSFETs, trench MOSFETs, or JFETs, are primarily of vertical configuration and have an internal diode that sets conditions for symmetric bidirectional current flow.
Power Supply Design Notes: How to Measure Ripple
2020年10月10日 · Introduction. The measurement of the output ripple in switching regulators is a crucial and delicate operation, for many reasons. Measuring this unwanted signal requires great care as it is easy to get erroneous readings. Ripple is an unwanted signal that is present at the output of the switching regulator.
