Abstract

The invention discloses a power factor correction circuit control parameters adjusting method and device, and air conditioner. The method for adjusting the control parameters of the power factor correction circuit comprises the following steps of acquiring preset control parameters of a proportional-integral controller in the power factor correction circuit; controlling the power factor correction circuit so as to run the preset control parameters; detecting whether the power factor correction circuit works abnormally or not; if the abnormal working of the power factor correction circuit is detected, adjusting the preset control parameters. Through the method, the device and the air conditioner disclosed by the invention, the problem that a product cannot go on normally running when the circuit is abnormal due to the fact that the control parameters of the power factor correction circuit cannot be adjusted adaptively in the prior art is solved.

Description

technical field [0001] The invention relates to the field of power electronics, in particular to a control parameter adjustment method and device for a power factor correction circuit and an air conditioner. Background technique [0002] With the wide application of various power electronic devices in power systems, transportation, industry, household and other fields, the problem of current harmonic interference and pollution of power grids has become increasingly prominent. Current harmonic interference will bring a series of hazards to the system itself and the environment of the power grid. Therefore, the problem of current harmonic interference polluting the power grid has gradually attracted people's attention. In order to suppress the current harmonics generated by power devices and reduce grid pollution, both domestic and foreign countries have restricted high-order harmonic interference in the form of legislation or promulgated national standards. Only electrical pr...
