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 […]
Achieving isolation in an isolation amplifier
Isolation amplifiers create a galvanic isolation barrier between input and output circuits to protect sensitive equipment and personnel from high voltages. Such isolation can be optical, capacitive, or inductive in an isolation amplifier. This FAQ will help us understand how each isolation type works and how they differ. How do optical isolation amplifiers work? Optical […]
How does DMA enable efficient data transfer in microcontrollers?
Direct memory access (DMA) allows peripherals to transfer data directly to and from memory without requiring the CPU to handle each cycle. As the CPU’s role is minimized, DMA enables the CPU to perform other high-priority tasks and ensures faster data transfers in the background. How does the DMA controller work to reduce the load […]
What are the different encoding techniques used for chipless RFID tags?
By Rakesh Kumar Encoding refers to converting a message into a different transmission, storage, or processing form. Chipless RFID lacks specialized ASICs to lower costs and use time and frequency domain systems for encoding. Hybrid encoding combines time and frequency domain systems for custom encoding options. A chipless RFID system is a radio frequency identification […]
What does a digital twin mean for a BMS?
A digital twin (DT) generally refers to a digital representation of a physical object, system, or process. The idea of creating a DT is to replicate a real-time model of a physical entity. While trying to make a real-time model, the various aspects of the physical entity, such as properties, behavior, and status, are considered. […]
How do Level 3 and wireless charging standards help reduce EV range anxiety?
Level 3, DC fast charging, is expected to help reduce range anxiety by speeding the EV charging process. However, fast DC chargers are expensive and can be challenging to connect to the grid. That’s expected to slow their widespread use. On the other hand, wireless power transfer (WPT) charging is currently limited to much lower […]
