“…In addition, the ZVS ''ON'' state of the main and clamp switches could be realized. As reported in [8], the active-clamp circuit suppressed voltage spikes observed on main switches, whereas the voltage drop across the clamp capacitor resulted in higher voltage gain. In [9], an isolated, bidirectional, dual-active bridge, seriesresonant DC-DC converter was proposed based on switching impedance.…”

To facilitate voltage matching between the cell stack and power batteries in fuel-cell-powered vehicles, an implementation of a simple dual-switch boost DC-DC converter topology has been proposed in this paper. Compared with existing boost topologies, the one proposed herein reduces the number of components required and stress induced whilst maintaining a high-gain ratio. The results of experiments performed in this paper reveal that the corresponding to a duty ratio of 0.8, the proposed converter topology demonstrates the realization of a boost ratio of 6, thereby exceeding that the realized by conventional boost converters by nearly 73%. In addition, at an output voltage of 50 V, a maximum operating efficiency of 91% was achieved. These results demonstrate the effectiveness and feasibility of the proposed DC-DC converter topology for use in fuel-cell-powered vehicles.INDEX TERMS Fuel cell, DC/DC converter, topology, high gain ratio.

“…A low voltage could, therefore, be achieved using a switch with a low ''ON''-state resistance. A nonisolated ZVS interleaved DC-DC boost converter was proposed in [8]. In this design, the energy stored within the leakage inductor could be recycled using a coupled inductor and active-clamp circuit.…”

This paper presents a nonisolated high step-up soft switching DC/DC converter with continuous input and output energy, low input current ripple, and low voltage stress of semiconductors. In this topology, passive clamping circuits are used not only to recycle leakage energy but also to successfully alleviate voltage spikes on the active MOSFET. The leakage inductor, on the other hand, solves the output diode's reverse recovery problem effectively. Furthermore, output capacitors are connected in series to supply the output load, resulting in a smaller output capacitor volume. The suggested topology's operational theory, as well as steady-state analyses, is thoroughly explored. The proposed topology's voltage gain and switch stress are then compared with that of some high-gain topologies. After this, a prototype circuit with a 20 V input voltage, 340 V output voltage, and 200 W output power is designed to test the proposed topology's accuracy.

“…The use of the current-fed CW-VM eliminates a few problems associated with conventional voltage feed types, such as voltage ripple and load-related voltage drops. In [15], a novel non-isolated ZVS interleaved DC-DC boost converter was proposed. This topology can effectively recycle and utilize the energy of leakage inductance.…”

DC/DC converters for fuel cell electric vehicles need not only high boost ratio and high efficiency, but also strong anti-jamming capability. Therefore, it is especially important to devise a control method with strong robustness under the premise of an appropriate topology. In this paper, a simple dual-switch boost converter topology is adopted. We use the state space averaging method to build a small signal model, and based on this model, we propose a feedforward-double feedback control system for continuous conduction mode (CCM) mode. Simulation and experimental results show that the proposed feedforward-double feedback control system improves the robustness of the system while ensuring a high boost ratio and efficiency, and solves the problem of weak output characteristics of fuel cells. The control effect is similar to the sliding mode control, which is known for its robustness, while the rise time of step response is only 1/10 of that of the voltage feedback control system. When the output voltage of the DC/DC converter is 55 V, the DC/DC converter using feedforward-double feedback control system is more robust than the voltage feedback control system under sudden change of load.
