NOVELTY - The aim of this invention is to develop a high-efficiency fuel cell high-boost-ratio DC/DC converter with voltage-clamped and soft-switching mechanism. Due to the electrochemical reaction, the fuel cell has the power properties of low voltage as well as high current. However, the fuel cell stack with high output voltage is difficult to fabricate and its volume is overlarge. Besides, the output voltage of the fuel cell is varied easily with respect to the variations of loads. In order to satisfy the requirement of high-voltage demand, a high-efficiency high-boost-ratio converter is one of the essential mechanisms in fuel cell applications. In this invention, a high-boost ratio DC/DC converter is designed on the basis of voltage-clamped and soft-switching techniques for alleviating the switching and conduction losses to increase the conversion efficiency. It can raise the voltage ratio in conventional boost converters and solve the leakage inductance problem of coupled inductor with high turns-ratio. Moreover, the closed-loop control methodology is utilized in the proposed converter to overcome the voltage drift problem of the fuel cell under the variation of loads. The novel converter developed in this invention has the salient features of rising the utility rate for energy and increasing the stability of power supply so that it can be used in the high voltage DC bus of a high-power inverter. In addition, it also can be utilized for other power generating types with low output voltage to provide a stable DC/DC power conversion.
