01 Basic Knowledge and Importance of Inductors
Inductors are components that can convert electrical energy into magnetic energy and store it. Their structure is similar to transformers but with only one winding. They have certain inductance, characterized by passing direct current and impeding alternating current. When current flows through a conductor, an electromagnetic field is generated. Inductance is a physical quantity that measures the ability of a coil to generate electromagnetic induction; when current is applied to a coil, a magnetic field is generated around the coil, with magnetic flux passing through. The larger the applied current, the stronger the magnetic field and the greater the magnetic flux. The ratio of magnetic flux through the coil to the applied current is proportional, and their ratio is called the self-inductance coefficient, which is inductance.

1. Why Do We Need Common Mode Inductors?
1.1 CAN bus interference mainly comes from common mode noise and differential mode noise. Common mode noise commonly includes ground loop interference and EMI (electromagnetic interference), which is generated simultaneously in both transmission lines, with potential referenced to ground.
For example: In complex electromagnetic environments, electromagnetic interference generated by nearby large electrical equipment during operation may enter the CAN bus through space coupling, forming common mode noise ; Differential mode noise is mainly signal crosstalk, generated between two transmission lines. For instance, during high-speed data transmission, signals from adjacent signal lines may interfere with each other, causing...

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.
