The main function of the battery management system (BMS) is to monitor cell voltage, battery pack voltage and battery pack current. In addition, given the high voltage design of the BMS, it is necessary to measure the insulation resistance between the high and low voltage domains to catch defects in the cell structure and prevent dangerous conditions from occurring.
BLDC motor is a rotary motor consisting of a three-phase armature winding on the stator and a permanent magnet on the rotor. The mechanical structure of the BLDC motor is opposite to that of the traditional permanent magnet brushed DC motor. The rotor is equipped with a permanent magnet and the stator is equipped with a motor winding. However, as the name suggests, BLDC motors have no brushes and require no regular maintenance or replacement, making them less susceptible to wear and tear
The power grid is designed to run on alternating current for a number of reasons, but almost every device needs direct current to operate. As a result, AC-DC power supplies are almost everywhere, and with increased environmental awareness and rising energy prices, the efficiency of such power supplies is essential to reduce operating costs and rational use of energy.
Traction inverters are the main component that consumes battery power in electric vehicles (EVs), with power levels up to 150kW or higher. The efficiency and performance of traction inverters directly affect the driving range of electric vehicles after a single charge. Therefore, in order to build the next generation of traction inverter systems, silicon carbide (SiC) field-effect transistors (FETs) are widely used in the industry to achieve higher reliability, efficiency and power density.
The artificial intelligence (AI) revolution has arrived. With the public release of applications such as ChatGPT, people are able to experience firsthand the power and potential of deep neural networks and machine learning (ML). ChatGPT is a language model that has been trained using massive amounts of text data from the Internet and books to generate text that resembles that written by real people.
With the growth of electric vehicles, the demand for small, precise position sensors in automotive applications will grow to $1.6 billion by 2026, tracking the position of rotors in motors responsible for traction machinery, power steering and Windows, and ensuring control and safety coverage. First, this paper reviews the traditional approach and position detection methods and their limitations
Semiconductor power devices mainly include power diode, power triode, thyristor, MOSFET, IGBT and so on. Among them, MOSFET and IGBT belong to voltage controlled switching devices, which have the advantages of fast switching speed, easy driving and low loss. The full name of IGBT is an insulated gate type power tube, which is a composite full-controlled voltage-driven semiconductor power device composed of bipolar triode (BJT) and MOSFET, and has the advantages of high input impedance of MOSFET and low on-voltage drop of BJT.
Modern battery-powered motor drive applications, such as power tools, are characterized by small size, light weight and low power, so solutions in this area of application must consider how to provide superior performance while occupying minimal system resources.
The concept of the Internet of Things (IoT) was first introduced in 1999. It describes a network of smart devices that use the Internet to improve human lives. For example, a car is equipped with various sensors that alert your phone when tire pressure is low. In addition to using a large number of sensors, the Internet of Things is also an arena for various wireless interconnection technologies, including cellular, Wi-Fi, BLE, NB-IoT, LTE-M, LoRa, Zigbee, NFC, and even satellite communication, which play a key role in the Internet of Things
The vast realm of space exploration has revolutionized our understanding of the universe. From probing distant galaxies to studying the composition of planets, space missions have revealed remarkable insights that expand our knowledge beyond Earth’s boundaries. Supporting these insights, space-grade electronic components play a pivotal role in enabling successful space missions. The significance of electronic components in space exploration cannot be overstated.
While it is true that manufacturers of components such as semiconductors are not environmentally friendly, electronic components in general play a key role in reducing humans' impact on the environment. From monitoring and managing environmental conditions to generating sustainable electricity and even monitoring nuclear fusion systems, advances in component circuits are propelling us towards a more sustainable future.
At present, microwave detection is widely used to detect the presence of the body in the magnetic induction region.
