Abstract

A transformer includes a magnetic component, a first winding group, a second winding group and a shielding component. The first winding group is windingly arranged on the magnetic component. The second winding group is windingly arranged on the first winding group. The shielding component is arranged between the first winding group and the second winding group.

Description

technical field [0001] The invention relates to a power conversion device and a transformer thereof. Background technique [0002] In recent years, electronic circuits are widely used in electronic devices, such as power conversion devices, that is, power supplies or power converters. However, since such circuits are often operated at high frequency switching, it is easy to generate Electro-Magnetic Interference (EMI), which further affects electronic devices. According to different transmission methods, EMI can be classified as Radiant There are two types of conduction (Conducted), radiated electromagnetic interference is transmitted directly from the open space, and conductive electromagnetic interference is transmitted through wires. [0003] Conducted electromagnetic interference can be divided into common-mode noise and differential-mode noise according to the different conduction paths of the noise current. The differential-mode noise is when the current directions of...
