Abstract

The invention provides a PFC circuit fault detection method and device, a terminal and a storage medium. The method comprises the following steps: applying an alternating current signal to a PFC circuit; independently applying a switching signal to the target switching module, and monitoring a direct current side electric signal of the PFC circuit at the moment; and if the direct current side electric signal of the PFC circuit changes in the switching period of the target switch module, determining that the target switch module is normal, otherwise, determining that the target switch module fails. According to the scheme, fault detection of the switch module in the PFC circuit can be realized, the problem that fault components in the PFC circuit cannot be positioned in the prior art is solved, and the accuracy of fault positioning is improved.

Description

technical field [0001] The invention relates to the technical field of PFC circuits, in particular to a fault detection method, device, terminal and storage medium of a PFC circuit. Background technique [0002] Currently, PFC (Power Factor Correction, power factor correction) circuits are widely used, and whether the PFC circuit can operate normally directly affects the reliable operation of related devices. Therefore, it is necessary to regularly overhaul the devices inside the PFC circuit. [0003] At present, when performing fault detection on a PFC circuit, it is usually only possible to detect whether the PFC circuit is faulty, and it is impossible to specifically locate the faulty components. Contents of the invention [0004] In view of this, the present invention provides a fault detection method, device, terminal and storage medium of a PFC circuit, which can solve the problem that faulty components of a PFC circuit cannot be accurately located in the prior art....
