Figure 1. Official execution and commencement of the road and river diversion project at the Sangdong Mine site in Korea

China produces 80% of the U.S. rare earths and has been doing so for quite some time. What makes things even worse is that over the past 12 to 18 months, a global pandemic has had a serious effect on the supply chain. People around the world rely on these rare materials in their everyday lives, and ma

Figure 1: Typical EV power conversion elements

Ask any power electronics designer what they strive for and top of the list is normally conversion efficiency. It’s not just for energy savings but also the knock-on benefits of smaller, lighter and cheaper products, with options opening up for better reliability and more functionality in space that’s freed-up. So

Figure 1: Si, SiC and GaN material characteristics

A basic building block in power conversion electronics is the semiconductor switch. The ideal is one with no static or dynamic losses that can withstand high voltage in the off state and with no leakage when on – but that is always just out of reach. One of the closest though is the wide band-gap technology Si

Figure 1: There are many choices when it comes to selecting the right plug for your external power adapter (Source: CUI)

New product features tend to have a direct impact on the total power needed, which may mean increasing the capacity of dc-dc converters or increasing the number of regulators distributed throughout the design. Ultimately, feature-creep will also put greater demand on the main source of power.  Engineers responsib

Figure 1. On the left is the TSPD functional model and, on the right, a TVS diode

With low-power, high-speed data systems, standard TVS diodes are commonly used in combination with low capacitance diodes to reduce the parasitic capacitance in applications like HDMI 2.0, USB 3.1, and Gigabit Ethernet. TVS diodes have offered the smallest form factors possible without sacrificing performance. Bu
