Abstract
A method, an apparatus and a computer device for detecting an open circuit fault are provided. The sample data of the electrical signal at the primary side of the transformer in the CLLLC resonant bidirectional DC/DC converter is performed with spectrum analysis to obtain a first frequency, and whether an open circuit fault occurs in the CLLLC resonant bidirectional DC/DC converter can be determined according to the first frequency and an actual switching frequency.
