1 Background of New Energy Vehicle Communication Networks
With the rapid development of new energy vehicles, the intelligence and automation level of vehicles continues to improve, making communication between electronic control units (ECUs) within vehicles increasingly critical. The communication network is like the "nervous system" of new energy vehicles, responsible for transmitting various control instructions and data information, ensuring coordinated operation of various vehicle systems.

In new energy vehicles, the battery management system (BMS) needs to communicate in real time with the motor controller (MCU), vehicle controller (VCU), etc., to achieve precise...

1. What is a TVS Tube?
 
TVS, or Transient Voltage Suppressor Diode, is a new type of highly efficient circuit protection device that plays a key role in preventing surge and overvoltage protection in electronic circuits. When the two ends of a TVS tube experience instantaneous high-energy impact, it can change the impedance between its terminals from high to low at extremely high speed (sub-nanosecond level), absorb a large instantaneous current, clamp the voltage across its terminals to a predetermined value, thereby protecting subsequent circuit components from transient...

In Boost circuits, selecting inductors requires considering the following key electrical parameters
 

Inductance value: According to the formula
 Calculate, where is input voltage, is output voltage, is diode forward voltage drop, is output current, and is switching frequency. Generally, larger inductance values result in better output voltage stability, but increase volume and cost2.
Current parameters:

Rated current: The inductor's rated current should be greater than the maximum continuous operating current in the circuit. It is generally recommended to select an inductor with a rated current 20%-30% larger than the circuit maximum current1.
Saturation...

In Buck circuits, selecting inductors requires considering the following multiple aspects:


Inductance value: According to the working principle and formula of Buck circuits

 

     
to calculate the required inductance value. Where is input voltage, is output voltage, is switching frequency, and is allowable inductor current ripple. Generally, larger inductance values can make output voltage ripple smaller, but will increase inductor size and cost, and may also reduce dynamic response speed; if inductance value is too small, it cannot effectively filter ripple, leading to unstable output voltage...

Skin effect in inductors refers to the phenomenon where when alternating current passes through an inductor element, the current concentrates on the surface of the inductor conductor, while the current density inside the conductor is smaller.
Principle of inductor skin effect
 

Electromagnetic induction effect: When alternating current passes through an inductor coil, it generates an alternating magnetic field inside and around the coil. According to Faraday's law of electromagnetic induction, this alternating magnetic field generates an induced electromotive force inside the inductor conductor, which in turn produces an induced current. Due to the larger rate of change of magnetic flux in the central part of the inductor, the induced electromotive force and induced current are also larger. These induced currents interact with the original current...

New Energy Vehicle Ethernet Protection

With the rapid advancement of new energy vehicle technology, traditional industrial Ethernet technology is also being widely used in the automotive industry. Automotive Ethernet provides the automotive industry with topology flexibility, high bandwidth, and anti-interference communication, making it an inevitable trend for the development of intelligent connected vehicles. In 2016, the IEEE standardized the automotive Ethernet system 100BASE-T1 and 1000BASE-T1 developed by the Ethernet Alliance Committee to meet specific requirements of automotive applications, especially in terms of electromagnetic interference (EMI) and electromagnetic compatibility (EMC).

On November 12, 2024, the biennial electronica exhibition in Munich, Germany, was grandly opened at the New International Expo Center in Munich, Germany. The exhibition, scheduled for November 12th to November 15th, 2024, stands as one of the premier events in the global electronics industry. It focuses on numerous cutting-edge fields such as automotive, wireless technology, medical electronics, and new energy, attracting over 3,000 exhibitors from around the world and more than 80,000 professional visitors, including technical experts and industry analysts. Yinte Electronics, as a mainstream semiconductor power device manufacturer in China, made its debut at this electronics industry event. Yinte Electronics

TOLL (Transistor Outline Leadless) packaged MOSFETs have been widely used in terminal applications such as electric bicycles, electric motorcycles, lithium battery protection, and communication power supplies due to their compact size, low package resistance, low parasitic inductance, and low thermal resistance characteristics. TOLL (Transistor Outline Leadless) package is an advanced power device packaging technology with multiple notable features and advantages. The following is a detailed analysis of the TOLL package: I. Basic Features

Source: Science and Technology News; About 20 years ago, Intel made the decision to change the course of computing history. In 2005, shortly after Apple installed Intel chips in Mac computers, Steve Jobs asked Paul Otellini, then CEO of Intel, if he was willing to supply iPhone processors, but was refused, causing a complete change in the future mobile computing architecture. Intel's decision 20 years ago enabled Arm to effectively monopolize chip design, with a market size in the mobile market that is more than twice that of the PC industry.
