“…The fuel cell output voltage is low and cannot directly drive the car motor, which requires a high DC bus voltage (e.g., 400 V) [4]. Therefore, in order to provide a stable output voltage to the load, the DC-DC converter with high gain, wide voltage input range and fast dynamic response speed should be used in fuel cell vehicles [5][6][7][8].…”

The DC–DC converter for fuel cell vehicles requires high gain and wide voltage input range to boost the voltage of the fuel cell. However, with the traditional boost converter, it is difficult to meet the requirements of the fuel cell vehicle power system. Based on a quasi-Z-source network DC–DC converter, this paper proposes a composite controller, which includes a feedforward compensation network and feedback control to meet the control robustness requirement of the fuel cell vehicle power system. The dynamic model of the converter is obtained by using the state space averaging method and the small-signal dynamic modeling method. The input voltage and load disturbance experiments are performed on the DC–DC converter. Moreover, the converter is tested under the worldwide harmonised light vehicle test procedure (WLTP) to validate the effectiveness of the proposed composite controller. The simulation and experiment results show that the proposed composite controller effectively enhances the converter’s ability to resist input and load disturbance, and improves the dynamic response performance of the DC–DC converter for fuel cell vehicles.

“…Scholars have carried out a series of research on FCVs in recent years. To apply dynamic low‐voltage fuel cell stacks to constant‐voltage DC‐bus FCVs, Bi proposed a wide voltage‐gain capacitor clamped H‐type boost DC‐DC converter suitable for FCV power interface. Li reviewed the hydrogen storage system of FCV comprehensively and analyzed the initial pressure, initial temperature, refueling speed, and environmental temperature, which promoted the development of FCV fast refueling technology.…”

A fuel cell vehicle (FCV) is composed of many subsystems; it is necessary to reallocate subsystem reliability to improve FCV system reliability. A comprehensive evaluation method considering uncertainty is proposed to obtain the interval value of feasibility factor. The FCV cost uncertainty model is established on the basic of parameters such as feasibility factor, initial reliability, limit reliability, and subsystem cost. To solve the optimization problem for cost uncertainty, the cost interval model is transformed into a deterministic model by interval order relation. An improved differential evolution (DE) algorithm is proposed to reallocate subsystem reliability for minimum cost.

“…Non-isolated high step-up DC-DC converters which employ several innovative techniques such as switched capacitors/switched inductors structures [10][11][12][13], cascaded converters [14,15], voltagelift [16,17], multilevel converters [18], coupled-inductor technique [5,[19][20][21][22], and voltage multiplier cells [23][24][25] are amongst the exemplary work in the literature to provide an alternative solution to isolated DC-DC converters. Several of these non-isolated high step-up DC-DC converters are derived from the conventional SEPIC converter [4,12,13,16,17,[20][21][22][24][25][26][27][28].…”

A new single-ended primary-inductor converter (SEPIC)-based DC-DC converter suitable for photovoltaic (PV) systems is introduced. The proposed converter has the advantage of continuous input current which reduces the input voltage ripple across the PV panels. Furthermore, it can provide a higher-voltage gain at smaller duty cycles when compared with counterpart SEPIC-based topologies which feature the absence of a coupled inductor. A smaller duty cycle for a given voltage gain translates to a lower-current ripple of the inductors, reduced conduction losses, and alleviated voltage stresses of the semiconductor switches. The proposed converter also benefits from a simpler structure and control scheme. The operational principles and the steady-state analysis are studied under both continuous conduction mode and discontinuous conduction mode. A comparative study between the proposed converter and seven counterpart topologies is also included. A laboratory prototype was built and tested. The experimental results are discussed in light of the theoretical analysis.
