POWER CONVERSION DEVICE AND AIR CONDITIONER - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17913871 Titled 'POWER CONVERSION DEVICE AND AIR CONDITIONER'
Simplified Explanation
The abstract describes a method to reduce noise that is emitted from a power conversion device. The device includes various components such as external electrodes, a switching element, a noise filter, and wires to connect these components. Additionally, a magnetic filter is attached to one of the wires. The goal is to reduce the noise that propagates outside of the device. The attenuation characteristics of the noise filter and the spatial coupling between the wires are measured and compared. It is found that the attenuation characteristic of the noise filter (A) is greater than the attenuation characteristic due to the spatial coupling between the wires (B). This relationship helps in reducing the noise effectively.
Original Abstract Submitted
A noise propagating to outside of a power conversion device is reduced. A power conversion device includes at least one external electrode, a switching element, a noise filter connected between at least one external electrode and switching element, at least one first wire to connect at least one external electrode and noise filter, a second wire to connect noise filter and switching element, and a magnetic filter attached to second wire. An attenuation characteristic A [dB] and an attenuation characteristic B [dB] satisfy a relationship of B<A, where A is an attenuation characteristic of noise filter, and B is an attenuation characteristic due to spatial coupling between at least one first wire and second wire that is located between switching element and magnetic filter.
