Taking the various sensors in the H-bridge converter as the research object, this paper makes a characteristic analysis of their disconnection fault. First, the MATLAB simulation model for 8 cascaded H-bridge converters is established in the paper; then, the disconnection faults of the capacitance voltage sensor, system voltage sensor, load current sensor and output circuit sensor are simulated herein respectively; at last, the impact of disconnection fault of different sensors on the key parameters of the system is analyzed. The analysis results show that the disconnection faults of the system voltage sensor and the output circuit sensor have a relatively large impact on the system’s key parameters. Therefore, certain measures must be taken to prevent the disconnection fault.
