Abstract

The invention discloses an electric power conversion device resistant to electromagnetic interference. The electric power conversion device is covered with a cover for electromagnetic shielding, the cover adopts a sandwich structure, specifically, a layer of foamed aluminum-copper-nickel alloy is sandwiched between two layers of permalloy plates, electromagnetic waves at low and high bands can be well shielded, meanwhile, pollution caused by electromagnetic radiation of the electric power conversion device to the environment is prevented, and interference of external electromagnetic waves to the electric power conversion device is reduced; further, super-hydrophobic structures of nanosheets are formed on surfaces of the permalloy plates of the cover through hydrochloric acid treatment, self-cleaning, anti-fog, anti-freezing and corrosion-resistant protection roles are played, and the service life of the electric power conversion device can be prolonged.

Description

technical field [0001] The invention belongs to the field of power conversion, and more specifically relates to a power conversion device resistant to electromagnetic interference. Background technique [0002] In our living environment, various electrical appliances such as TVs, microwave ovens, induction cookers, computers, mobile phones, etc. will generate electromagnetic waves, and electromagnetic waves emitted by radio stations, TV stations, satellite communications, etc., all exist in our living environment. While enjoying a convenient life, we are also living with electromagnetic waves day and night, coexisting peacefully. However, with the development of modern technology, the impact of electromagnetic radiation on the environment is increasing. On the one hand, electromagnetic radiation will affect people's health and cause serious interference to the surrounding electronic equipment. On the other hand, electromagnetic radiation will Disclosure of information, so t...
