Because of their compact size, higher efficiency, and superior performance in high-power applications, SiC MOSFETs are now replacing Si devices in switching applications. SiC devices enable faster switching times, significantly reducing switching losses. These advantages stem from the unique electrical and material properties of SiC-based devices — snappy reverse recovery inherent to the structure of […]
FAQ
How does the shape of the coil affect wireless power transfer?
Coil shapes have played a profound role in the performance of wireless power transfer, especially with the coupling coefficient, output power, and energy transmission. We will examine how square, circular, and pentagonal coils have fared against each other. While there are many more shapes, these three form the basis of other shapes and, therefore, require […]
How do modular wiring harnesses support zonal architectures?
Vehicle wiring harnesses without a zonal architecture can have over 1,000 wires connecting over a hundred ECUs. They are difficult to fabricate and install, and changes can be difficult and costly to implement. However, using modular wiring harnesses in zonal architectures can overcome those challenges. A zonal architecture places electronic control units (ECUs) in multiple […]
Where are LPWAN protocols used?
LoRaWAN, Wi-Fi, ZigBee, and LP-WAN are wireless protocols used by IoT and IIoT devices. Low-Power Wide-Area Network (LPWAN) is a wireless technology specifically developed for Internet of Things (IoT) connectivity and machine-to-machine (M2M) communications. As Figure 1 illustrates, LPWAN enables a diverse range of applications. This article reviews the key advantages and limitations of LPWAN,…

How to determine noise figure: part 1
A noise figure consolidates the effects of various noise types to provide a single specification for the noise performance of a component or system. In electronic circuits and systems, noise is an undesirable, inevitable disturbance in currents and voltages. Noise has many underlying fundamental causes. Thermal noise, also known as Johnson–Nyquist noise, results from random […]
Bipolar junction transistors show their muscle
Recent enhancements to the classic BJT show that the classic transistor has plenty of life left and can challenge SiC and GaN devices in some power applications. Amidst the advances in CMOS and wide bandgap semiconductor technology, you can easily forget that the first transistor invented by William Shockley in 1949 was a bipolar junction […]
What’s the difference between mini delta ribbon and shrunk delta ribbon cable assemblies?
Mini delta ribbon (MDR) and shrunk delta ribbon (SDR) cable assemblies are both designed to carry video signals as specified in the Camera Link (CL) specification, and they have the same internal connections. MDR and SDR cables are incompatible with the higher speed Camera Link HS (CLHS) standard. CLHS connectors include CX4 and SFP/SFP+. A […]
What are the seven variations of Camera Link Machine Vision connectivity?
Camera Link (CL) standardizes the hardware connection between cameras and frame grabbers. It includes specifications for data transfer, camera timing, serial communication, and real-time signaling. Camera Link variants include base, medium, full, deca, high speed (CLHS), PoCL (power over Camera Link), and PoCL Lite. Camera Link is a serial communication protocol standard maintained and administered […]
