High voltage gain dc-dc converters plays an major role in many modern industrialized applications like PV and fuel cells, electrical vehicles, dc backup systems (UPS, inverter), HID (high intensity discharge) lamps. As usual boost converter experiences a drawback of obtaining a high voltage at maximum duty cycle. Hence in order to increase the voltage gain of boost converter, this paper discusses about the advanced boost converter using solar power application. By using this technique, boost converter attains a high voltage which is ten times greater than the input supply voltage. The output voltage can be further increased to more than ten times the supply voltage by using a parallel capacitor and a coupled inductor. The voltage stress across the switch can be reduced due to high output voltage. The Converter is initially operated in open loop and then it is connected with closed loop. More over the fuzzy logic controller is used for the ripple reduction.

In this paper, a high step-up DC/DC converter is proposed, which can boost low PV panel voltage or battery voltage to a high level so as to power the dc side of gridconnected PV inverter. The proposed converter is composed of an inductor, a power switch, and a coupled inductor and is derived from the integration of buck-boost and flyback for high voltage-gain achievement. Even though it possesses buck-boost and flyback features, there is no the problem of reverse voltage polarity and the energy stored in the leakage inductance can be recycled without additional active clamp circuit. Furthermore, since the input source, active switch, and output port are in common ground, the proposed converter has the advantages of easy control-circuit design and simple control-circuit configuration. In particular, the proposed converter can be expanded to multi-layer topology to stack up output voltage such that a much higher voltage gain can be obtained. A prototype, of which input voltage is 48V, output voltage is 400V and power rating is 200W, is built to validate the proposed converter. Experimental results have verified the feasibility and functionality of the proposed converter.

“…Up to now, various hybrid topologies and control methods of converters have been suggested to interface an FC stack to different loads by using energy storage devices [8]. High efficiency and performance, high power density and fast transient response, and reduction in FC system volume are favorable characteristics of a FC hybrid power system [9].…”

This paper depicts a new configuration for modular hybrid power conversion systems, namely, multi-hybrid generation system (MHGS), and parallel connection at the output, such that the converter of each unit shares the load current equally. This is a significant step towards realizing a modular power conversion system architecture, where smaller units can be connected in any series/parallel grouping to realize any required unit specifications. The supercapacitor (SC) as a complementary source is used to compensate for the slow transient response of the fuel cell (FC) as a main power source. It assists the Fe to meet the grid power demand in order to achieve a better performance and dynamic behavior. Reliable control of the proposed MHGS with multiple units is also a challenging issue. In this paper, a simple control method to achieve active sharing of load current among MHGS modules is proposed. The simulation results verify the performance of the proposed structure and control scheme.
