“…Boost converters' efficiency can reach above 90% under optimal conditions [111]. The average lifetime of boost converters is more than 20 years [112]. Figure 6 shows the schematic of a boost converter, where L is the input inductor, C is the output capacitor, I L is the inductor current, V in is the input voltage, and V out is the output voltage.…”

This paper introduces a medium voltage direct-current (MVDC) system for large spacecraft megawatt-scale (MW) power and propulsion systems intended for interplanetary transport, including missions to the Moon and Mars. The proposed MVDC system includes: (i) A nuclear electric propulsion (NEP) that powers a permanent magnet (PM) generator whose output is rectified and connected to the MVDC bus. (ii) A solar photovoltaic (PV) source that is interfaced to the MVDC bus using a unidirectional boost DC-DC converter. (iii) A backup battery energy storage system (BESS) that connects to the MVDC bus using a bidirectional DC-DC boost converter. (iv) A dual active bridge (DAB) converter that controls the power to the spacecraft’s electric thruster. The NEP serves as the main power source for the spacecraft’s electric thruster, while the solar PV and BESS are intended to provide power for the payload and spacecraft’s low-voltage power system. The paper will (i) provide a review of the spacecraft MVDC power and prolusion system highlighting state-of-the-art main components, (ii) address the control of boost converters for the PV and BESS sources and the DAB converter for the thruster, and (iii) propose an uncertainty and disturbance estimator (UDE) concept based on current control algorithms to mitigate MVDC instability due to unpredictable factors and external disruptions. The proposed UDE can actively estimate and compensate for the system disturbance and uncertainty in real time, and thus, both the system tracking performance and robustness can be improved. Simulation studies have been conducted to substantiate the efficacy of the proposed schemes.

With the continuous development and progress of industrial technology, the fossil fuel reserves of the earth are decreasing day by day, and it is more and more difficult to maintain the current energy demand. All sectors of the world are looking for an effective alternative to traditional energy. Hydrogen, known as the clean fuel of the 21st century, has gradually come into people's view because of its high combustion heat value and no pollution of the products after combustion. This paper discusses construction characteristics and working principle of fuel cell vehicles, to prove that the environment problems can be reduced by them. It first introduces the advantages of fuel cells, it produces almost no pollution, thus alleviating the greenhouse effect. It is of the main reasons why FCVs are becoming more and more popular. Secondly, the author also introduces the structure of fuel cell vehicles by comparing their similarities and differences with ordinary cars. The control systems of fuel cell vehicles have also been introduced.

In the last few decades, the utilization of fuel cells (FCs) in the automotive industry has created much attention due to easy use, modular structure, and higher efficacy. In the future, technological evolutions reveal that FC driven electric vehicles (EVs) will grow at a rapid pace and will become an excellent alternative to conventional vehicles. This paper discusses a detailed topological classification of the FC‐based hybrid electric vehicle (FCHEV). In these FCHEVs, one of the critical elements is the DC–DC power converter unit. The hybridization of FCs with the other power sources requires more converter units that make the system complex. A multi‐input DC–DC power converter is used to connect more than one energy source to reduce the system's complexity and improve the overall system efficacy. In this survey, numerous articles have been considered and examined vividly. An assessment of present and future scenarios of FCs based power source topologies and multi‐input DC–DC power converter topologies used in HEV is presented. This survey provides a deep insight into the topic for the researchers and engineers working in this field.
