Dynamic voltage and frequency scaling (DVFS) is an effective method for controlling both energy and performance of a system. Since the increasing rate of radiation-induced transient faults depends on operating frequency and supply voltage, DVFM techniques are recently shown to have compromising advantages on electronic system reliability. Therefore, ignoring the effects of voltage scaling on fault...
This paper identifies a new fault type of non-regenerative three-level boost rectifiers (Vienna-type rectifiers), namely the dc-link voltage-doubling fault. Under this failure mode, the voltage across the dc-link capacitors is doubled when any of the ac switches in the neutral path of the converter is shorted, a unique behavior of three-level neutral-point clamped topologies. Addressing this, two...
This paper presented a systematic analysis of the protection methods for paralleled VSCs system especially with common DC bus from four types of internal faults, including short or open circuit faults of single switch or diode. The potential damages of such faults relating to circulating current were first explained. After that internal faults detection and isolation schemes based on de-saturation...
