In recent years, fault tolerance has gained a growing interest from the scientific community, particularly in DC/DC converters. Generally, fault‐tolerance refers to a fault‐tolerant topology and/or control for power converters. In this paper, a floating interleaved boost converter (FIBC) is used in order to meet the fuel cell requirements, particularly in terms of input current ripple reduction and reliability. In DC/DC converters, power switches are ranked as the most fragile components. The most common failures in power switches are open‐circuit faults (OCFs), gating faults and short‐circuit faults (SCFs). The loss of one leg in case of OCF or SCF (considering that the faulty leg is isolated before damaging the system) leads up to the drastic increase of the fuel cell current ripple and consequently fuel cell lifespan reduction. The purpose of this paper is to present a fast and efficient power switch open‐circuit fault detection algorithm and fault‐tolerant control (FTC). The performances of the developed fault detection algorithm and FTC are validated by carrying out experimental tests between a proton exchange membrane fuel cell and a FIBC topology. The experimental results demonstrate the ability of the developed FTC to reduce drastically the fuel cell current ripple while improving the fuel cell lifespan.

When medium-or high-voltage power conversion is preferred for renewable energy sources, multilevel power converters have received much of the interest in this area as methods for enhancing the conversion efficiency and cost effectiveness. In such cases, multilevel, multi-input multi-output (MIMO) configurations of DC-DC converters come to the scenario for integrating several sources together, especially considering the stringent regulatory needs and the requirement of multistage power conversion systems. Considering the above facts, a three-level dual input dual output (DIDO) buck-boost converter, as the simplest form of MIMO converter, is proposed in this paper for DC-link voltage regulation. The capability of this converter for cross regulating the DC-link voltage is analyzed in detail to support a three-level neutral point clamped inverter-based grid connection in the future. The cross-regulation capability is examined under a new type of pulse delay control (PDC) strategy and later compared with a three-level boost converter (TLBC). Compared to conventional boost converters, the high-voltage three-level buck boost converter (TLBBC) with PDC exhibits a wide controllability range and cross regulation capability. These enhanced features are extremely important for better regulating variable output renewable energy sources such as solar, wind, wave, marine current, etc. The simulation and experimental results are provided to validate the claim.

Summary In this paper, reliability evaluation is proposed for some of the most famous impedance network‐based DC‐DC boost converters. Markov reliability approach is used to evaluate the reliability of the converters. Also, some other factors such as components' failure rates, reliability functions, and mean time to failures are introduced and evaluated. Detailed explanations for the evaluation methods of the mentioned factors are also provided in the context of the paper. In addition to the mathematical analysis, numerical calculations are also done through the simulation results of the converters. Simulations are done in PSCAD/EMTDC. Finally, a numerical and graphical reliability comparison is provided for the mentioned converters. The purpose of this paper is to give a comprehensive reliability evaluation and comparison for some of the most popular impedance network‐based DC‐DC converters. In addition, this paper gives a detailed reliability analysis that can be used in reliability assessment of all types of power electronic converters, so it can help the researchers to consider reliability calculations into their designing.
