Robust Fault Detection of Hybrid Switched-Capacitor Dickson Converter for Fault-Tolerant Automotive Applications

This paper presents short-circuit and open-circuit fault detection schemes for power switching devices and flying capacitors in a hybrid Dickson dc-dc converter. The methods only rely on the switching-node voltage characteristics, which eliminates the need for high-voltage sensing circuitry. The performance of the design is verified using a 36-W four-phase 48-to-3.3-V 4-to-1 hybrid Dickson converter prototype.
