Before starting the order,  Please tell us wire diameter, magnetic ring size, number of turns, inductance value.

Magnetic components are usually composed of windings and magnetic cores. They are necessary power electronic components for energy storage, energy conversion and electrical isolation. They mainly include transformer and inductor. Magnetic components are indispensable in almost all power circuits. Magnetic components are one of the most important components of power electronics technology.
Although magnetic components such as electronic transformers and inductors are just some seemingly insignificant small parts, they play an indispensable role in new energy vehicles, LED power supplies, photovoltaic inverters and other products. Generally speaking, electronic transformers play the role of transformer, filter and energy storage in products, while inductance is to solve EMI problems, electromagnetic compatibility and so on.


New energy vehicles
In new energy vehicles, magnetic components such as electronic transformers and inductors are mainly used in automotive electronics. Compared with traditional automotive electronics, new energy automotive electronics use more electronic transformers, inductors and other magnetic components than traditional ones, because like traditional automobiles, in addition to multimedia, high-frequency signal processing, etc., it will not use high Frequency capacitors, inductors, or similar frequency-increasing devices.
 New energy automotive electronics require magnetic components to pass experimental tests such as anti-interference, static electricity, durability, high and low temperature, vibration, EMC (tests related to automotive electronic components). EMC will clarify the requirements for space, quality, size, etc. of magnetic components, and the specific parameters and power range depend on the EMC compliance level of the product.
Involving the standards that magnetic component manufacturers should meet for products, there are mainly the following requirements. First, the inductance of the product must meet the error accuracy; second, whether the current can meet the requirements, some of the inductance is relatively large, then its current is also It will be relatively large. If it is done well, the loss of the product will be small; the third requirement for material and technology, such as the requirement for copper wire in material, and the winding of technology.
Drive power
The magnetic components required for LED drive power supply mainly include transformers, common mode inductors, power inductors, etc. These components have higher quality requirements than traditional power supplies, because LED lights require higher temperatures than ordinary lights. The transformer plays the role of transforming voltage in the power supply, and the inductance is to solve the problem of EMI, so the magnetic component is very important, and its basic consumption accounts for between 1/4 and 1/5 of the entire power supply.
LED drive power requires electronic transformers, inductors and other magnetic components to be small in size, good in performance, high in stability, and low in loss. The key to magnetic components such as electronic transformers and inductors is to optimize the magnetic core and increase the density and parameters of the magnetic core.
Photovoltaic inverter
Inverters play an important role in solar photovoltaic power generation systems, and magnetic components are the basic components of inverters. Electronic transformers are used in the inverter to control power supply and grid connection, in addition to sensors and other related magnetic components. The use of these magnetic components in photovoltaic inverters will reach about 20% of the usage. They are mainly used in inverters to play the role of filtering, voltage transformation, electromagnetic compatibility and so on.
Photovoltaic inverters have requirements for the conversion efficiency, volume, weight, and cost of magnetic components, as well as the heat generation and loss of performance are also very important.
As a manufacturer, the components are required to achieve high efficiency, low loss, low noise, long life, insulation and withstand voltage, and the volume should be as small as possible. As a user, the lower the cost, the better, and the higher the efficiency, the better. If my country's magnetic component manufacturers want to produce better products, first, they must work hard in technical theoretical research, new material application, and design level; second, they must strengthen the process, including product consistency and stability.
