Power transformers play a vital role in the transmission and distribution of electrical power. They are responsible for step-up and step-down voltage conversion, ensuring efficient and reliable electricity supply. The design and development of power transformers involve several critical technological challenges. In this technical blog, we will explore some of the key obstacles faced by engineers in power transformer design.

​As the world moves towards a more sustainable future, the new energy vehicle (NEV) industry has gained significant momentum. Electric vehicles (EVs) are at the forefront of this revolution, with their increasing popularity and adoption. One crucial component that plays a vital role in the development of EVs is the voltage transformer. In this blog post, we will explore the application prospects of voltage transformers in the NEV industry from the perspective of a university professor.

power transformers are widely used in several fields. Industrial automation: Power transformers are extensively used in industrial production to supply different voltage levels for various electric equipment such as motors and robots. Medical equipment: Medical devices like X-ray machines, magnetic resonance imaging (MRI) system, electrocardiogram (ECG) machines require a stable power supply, and power transformers play a significant role in providing it. Additionally, portable medical devices also use power transformers for charging.

The design of switching power transformer is divided into three aspects: reduce the loss of switching transformer as far as possible; Minimize leakage of switching transformer; Try to suppress the audio noise of the switching transformer.

Telecom Transformer products are widely used in cable modem, network card, hub, xDSL broadband communication equipment, switch, optical transceiver, router, embedded system, VoIP and other network communication equipment, data communication equipment, photoelectric transmission equipment, access network equipment, power line Internet equipment, voice equipment, etc

The audio transformer can realize voltage-converter conversion just like the power transformer, and can also realize audio signal coupling. There are four main functions of audio transformer:Output transformer: used in audio equipment and playback equipment, impedance conversion in the circuit.

Isolation transformer belongs to the safety power supply, generally used for machine repair, maintenance, protection, lightning protection, filtering function. The principle of isolation transformer is the same as that of ordinary transformer. They all use the principle of electromagnetic induction. Isolation transformers generally (but not all) refer to 1:1 transformers.

the structure of the power transformer:(1) Rectifier；(2) Filter；(3) Inverter；(4) Power factor correction:

A power transformer is a static machine used for transforming power from one circuit to another without changing the frequency. As there is no rotating or moving parts, a transformer is classified as a static device. Transformer operates on an AC supply. Transformers operate based on the principle of mutual induction.
