“…However, the system still lacks a complete emergency shut-down procedure of battery system to make it fully functional for the practical applications. Interleaved DC-DC converters inherently have FT capabilities because of its redundant architecture and can be used to provide uninterrupted power [65]. Every control scheme for interleaved DC-DC power converter strives to improves the output voltage regulation as well as the current sharing of SMs.…”

As the power interface between the energy storage devices (ESD) and the dc link of DC Micro-grids, dc-dc converters, which have been regarded as the heart of many critical applications such as electrical vehicles, data center, and aerospace power systems, have gained more and more attentions recently. The fault diagnosis and tolerant control in dc-dc converters become essential to ensure a reliable and robust power system especially for critical applicants, where a sudden stoppage, loss of functionality, or degradation of performance might result in a catastrophe. This paper focuses on different types of faults in dc-dc converters by analyzing main failure spots and mechanism, covering catastrophic fault and parametric fault from component to system. A comprehensive review of the up-to-date fault mode analysis, fault diagnosis signals and algorithms, and fault tolerant control in various dc-dc topologies has been presented. This research will provide a useful design guideline for the reliability improvement in all forms of dc-dc converters.

“…A model‐based method for OCF fault detection in IBCs has been suggested in [10]. This approach is applicable only when the output voltage of the converter is controlled through a dual‐loop controller in which the outer loop determines the current setpoints for the inner loops which regulate the phase currents.…”

This paper presents a novel algorithm for fault diagnosis and fault tolerant control of interleaved boost converters (IBCs) in the presence of single or double simultaneous open‐circuit faults (OCFs) in power switches. An innovative diagnosis signal (recorded by a cheap current sensor) will be introduced whose waveform mainly depends on the healthy or faulty condition of the converter. Since the diagnosis signal is periodic in the steady‐state operation of the converters, its Fourier Series coefficients, together with the duty cycle of the converter are used as distinguishing features for fault diagnosis of the OCFs in the converter. The well‐known Kalman filter is utilized for robust estimation of the Fourier‐based features. Finally, the modulation of the remaining healthy phases is rearranged in a way that the pre‐fault performance recovers. The proposed algorithm is verified in a laboratory four‐phase IBC setup in which the experimental results show its satisfactory performance. Also, the structure of the proposed method is straightforward and can be implemented in the same microcontroller which is used for voltage and current regulation of the converter.

“…are under significant influence from environmental factors, such as temperature, which are not suitable for our design. In [6][7], a fuse is integrated into the ground connection of power transistor, the fuse will blow out when it reaches the maximum current during short circuit, and the short circuit can be transformed open circuit for analysis. However, the author believes that if a fixed current is set as the basis to determine short current, it will take certain time for the current to reach the preset maximum current.…”

“…There are many classified discussions, which are very difficult for analysis, and it will become more complicated after being extended to higher order of interleaving. [9] provides an adjustment strategy after fault, which also deserves further investigation. In [10][11], based on the shape of inductor current, the detection and fault diagnosis are conducted by the single fieldprogrammable gate array (FPGA), which can realize recognition and handling of short-circuit and open-circuit faults of a power transistor.…”
