Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to an active filtering device capable of wireless communication. Background technique [0002] With the rapid development of power electronic technology, various power electronic devices are more and more widely used in industry. The operation of these nonlinear loads seriously distorts the voltage and current waveforms in the grid, and the harmonic levels continue to rise. Among them, current harmonics are the main cause of voltage harmonics and damage to electrical equipment. Therefore, finding a method to effectively suppress current harmonics has been a hot research topic at present. [0003] There are mainly two types of methods to suppress current harmonics: one is active control, through the transformation of power electronic devices so that they do not generate harmonics, and the power factor is controlled to 1, such as a typical power factor correcti...
