“…In OCF, after the fault detection the faulty switch can be restored with a redundant switch, whereas in SCF the reconfiguration of the converter will happen only after the faulty switch is disconnected [40]. A comparison between the delayed version of gating signals and the sign of the inductor current slope is used as fault diagnostic to identify both OCF and SCF in non-isolated DC-DC boost converter [41]. However, still the same approach can be applied to any other non-isolated single switch DC-DC converters including buck, buck-boost, Cuk, SEPIC and dual SEPIC converters.…”

The DC-DC converters operate extensively in a variety of industrial applications such as electric vehicles, renewable energy systems, aerospace applications, consumer electronics (smartphones, laptops, etc.) and energy storage solutions. The reliability of the DC-DC converters is of a greater significance. The research endeavours made in enhancing the reliability of the DC-DC converters are still very limited and dispersed. Due to the rapid growth in semiconductor technology, the DC-DC converters have an endless number of topologies, with various operating principles and functionalities. Enhancement of the reliability of all types of DC-DC converters is still a challenging task. Power switches are the most fragile components in converter circuits, which inherently fall prey to the faults occurring in the system. Hence, there is always a requirement to take appropriate remedial measures to deal with all kinds of faults. Further, in order to detect the occurrence of fault a fast faultdiagnosis and fault-tolerant strategies in the DC-DC converters is mandatory and the same has to be embedded in the converter for safety purpose. In view of the importance of the same, the fault-diagnostic algorithms and fault-tolerant strategies developed in the literature, by various researchers are furnished in a single document after conducting an exhaustive review.

“…To slightly improve the diagnostic effectiveness, the non-ideal response of the converter is considered in the implementation of another derivation of the original algorithm. The fault diagnostic action compares the sign of the inductor current slope and a delayed version of the gating signal, characteristic of the non-ideal converter [9] . Supported on the same diagnostic principles, simpler strategies, requiring less computational effort, were developed.…”

DC-DC converters are becoming more commonly used in power conversion solutions for energy management purposes, being employed in an ever-increasing range of DC-based applications, such as LED lighting, electric vehicles, energy storage solutions, and consumer electronics (laptops, smartphones, etc.). In this context, efficiency and reliability are critical. The research efforts made in improving reliability of DC-DC converters are still quite narrow and scattered. Moreover, DC-DC converters take the shape of an endless number of topologies, with different functionalities and operation principles, thus complicating the task of improving reliability of all forms of DC-DC converters. Consequently, compiling the information about the main failure modes, corresponding fault diagnostic algorithms and fault tolerance strategies developed so far, in a single document, becomes increasingly necessary. Accordingly, this paper presents an up-to-date review of the recent achievements attained regarding the improvement of availability and reliability of DC-DC converters.

Major faults arise in power converters mainly due to faulty MOSFET switches, diode and electrolyte capacitors. Converter with fault tolerant circuit improves the overall reliability of DC‐DC converter. We develop a self‐test configuration that identifies the faults in analog to digital converter (ADC), DC to DC converter and battery. IEEE 21451 standard‐based interface is implemented to develop a knowledge‐based smart controller. The centralized controller is performed to execute the maximum power point tracking (MPPT). Photovoltaic (PV) energy storage system is constructing to prove how the converter’s sensing, processing, and actuation capabilities in actual time may allow effective fault identification. The simulation result of the proposed method is executed in the MATLAB/Simulink working platform. The experimental results are implemented with field‐programmable gate array of Spartan‐6 Xilinx. The simulation as well as experimental result shows different fault identification in PV with energy storage system. Battery is provided through 12 V/4.5 Ah battery. The simulation and experimental results make ensure that the proposed method reveals its proficiency. It shows that the received results may fault identification at less than the period of one switching usually by 100 ms with suggested method.
