The main purpose of this article is to study the sensor fault isolation for DC-DC converters, taking the single-ended primary industry converter as an example. To achieve the purpose of the research, we model the DC-DC converters as switched affine systems and design a bank of sliding mode observers for each corresponding sensor fault. By comparing the threshold with the residual estimation function produced by each sliding model observers, we can diagnose which sensor faults are occurring. Finally, three sensor faults are given as simulation examples to verify the feasibility of the proposed scheme.
