What are the differential and common-mode impedances of the RF transformer?

The test of the RF transformer can be treated as a balun, and the test can be completed by combining the port extension (offset) and virtual differential mode of Yanet.Although it can be used as a balun, the RF transformer is still quite special because it has an impedance conversion ratio, such as

Planar Transformers Facilitate DC/DC Converter Design

For a long time, transformers have been a pain point and difficulty for DC/DC converter designers. Because they are bulky, expensive and difficult to manufacture. By reading this article, you can understand how planar transformers can improve the quality and reduce the design cost of low power DC/D

What is a transformer? Learn Transformers Using an Oscilloscope

What is a transformer? A transformer (transformer) is a device that converts electrical energy into magnetic energy, and then converts magnetic energy into electrical energy. Transformer diagram The transformer can be upgraded Voltage, step-down, can also k

Switching power transformer structure and composition

Simple working schematic diagram of the most basic flyback transformer switching power supply. In this circuit system, Ui is the input voltage of the switching power supply, T is the switching transformer, K is the control switch, C is the energy storage filter capacitor, and R is the load resist

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

Causes and Corrective Measures of EMC Electrical Fast Bursts Affecting Equipment

Electrical fast burst There are three reasons for the impact on equipment.( 1) The power supply of the device is directly conducted through the power supply line, resulting in excessive noise voltage on the power line of the circuit. When the interference source is injected into the live wire or the

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

Key Points of Winding in Manufacturing Process of High Frequency Transformer

A、Determine the parameters of BOBBINB、All windings are required to be flat and non-overlapping.C、A single set of winding wires can be single-color wires, and double-set winding wires must be divided into two-color wires or open wires soaked in tin to avoid wrong windingD、The

High Frequency Transformer Design Principles

When designing a high frequency transformer, the leakage inductance and distributed capacitance of the transformer must be minimized, because the high-frequency transformer in the switching power supply transmits a high-frequency pulse square wave signal. During the transient process of

What is a high frequency transformer

High-frequency transformer is a power transformer whose working frequency exceeds intermediate frequency (10kHz). It is mainly used as high-frequency switching power transformer in high-frequency switching power supply, and also used as high-frequency inverter in high-frequency inverter po
