چکیده انگلیسی
In this study, a novel all-purpose high-power matching device is proposed to be utilized in energy conversion applications. It is a 6 kW matching device with a low-cost structure consisting of three distinct stages that a complementary pair of unity-gain current mirrors has been utilized in each stage to provide appropriate output currents and voltages. The proposed device is the first and only all-purpose high-power matching device reported in the literature that can be widely used in energy conversion systems to minimize the cost of construction and maintenance. For instance, it can be utilized in a hybrid power generation system including different power sources such as photovoltaic array, fuel cell stack and battery to directly couple the power sources to each other. While, in the conventional method, the power sources are connected to a common Direct Current-link bus via several converters that significantly imposes extra cost. A prototype of the matching device has been built, and simulation and experimental results are presented to model its behavior at low and high frequency. To show some applications of the matching device, it is first utilized as an adjustable high-power (Direct Current)/(Direct Current) converter which is widely used in electric/hybrid vehicles. As the second application, a photovoltaic/fuel cell hybrid power generation system equipped with a maximum power point tracking controller has been built, and the matching device has been used as an interface unit to connect in parallel a fuel cell stack to a photovoltaic system.
