Why do Ethernet interfaces need a network transformer?

How Network Transformers Work Network transformers are also known as "data mercury", or network isolation transformers. Plays two main roles in the network interface: one is to enhance the data transmission of the differential signal transmitted by the PHY through a filter that combines differenti

Low consumption and low power 10W power supply chip U9513B

Low power consumption and low power 10W power supply chip U9513BWith the advent of single-chip control switching power supply, switching power supply adapters have also surpassed power frequency transformer adapters with a strong momentum of development. This phenomenon is more obvious in the field

Talk about space vector control and tracking control technology in PWM

01Space vector SVPWM controlSpace vector SVPWM control technology is widely used in inverters. The chain becomes a circular rotating magnetic field, which causes the motor to generate a constant electromagnetic torque.Three-phase voltage bridge inverter circuitUsing 180° conduction mode, there are

Why does it affect the work of other electrical equipment when the motor starts?

Let’s summarize the existing answers first: (Please add if you haven’t said everything) 1. The power of the motor is greater than 10kW; 2. The power of the motor is greater than 50kW; 3. The power of the motor is greater than 20% of the transformer capacity; 4. The voltage drop caused by the motor

Multisim simulation - capacitance measurement circuit

Digital Capacitance Tester:Capacitance is an essential electronic component in electronic design. It is widely used in electronic design. There are many types of capacitance, and the values of different types of capacitance From a few pf to a few F, it is very important to clarify the capacitance va

Ten common problems and solutions when debugging switching power supplies

1. Transformer saturation Transformer saturation phenomenon: Start up under high voltage or low voltage input (including light load , heavy load, capacitive load), output short circuit, dynamic load, high temperature, etc., the current through the transformer (and switch tube) increases nonlinearl

Discussion on motor resolver (1)

The sensor as a sensing device plays an absolute role in the control. Reminiscent of motor controller, it generally contains temperature sensor, currentvoltage sensor, and is directly related to the electric control The motor also has a position sensor, which is what we often call a resolver, or res

Discussion on the working principle of resolver (2)

Continue to talk about the rotation. In the previous article, we learned about Ampere's law and Faraday's law of electromagnetic induction. Two new terms are introduced today: Hall effect and magnetoresistance effect. 01.Hall effect and magnetoresistance effectMagnetoresistance The definition of Mag

Talk about how the power supply works inside

In the process of power supply design and debugging, when we encounter problems, we should put our thoughts into the inside of the power supply, and if we are in the power control part, what should we do if we encounter such problems? solve. That is to consider the problem from the perspective of th

Basic Switching Power Supply Topology (3) - The Essence of Topology

Fourth, basic switching power supply topology analysisFor switching power supply topology: inductor, switching tube The node between the diode and the diode is called the switching node; after the current flows into the node from the inductor, it can either flow out of the diode or the switch tube (
