Abstract :

Because the traditional fossil energy is not renewable modern societies, are facing energy shortages. As a result, it is necessary to develop new energy that is clean and renewable to replace of fossil fuels. Solar energy, photovoltaic power generation, fuel cell and hydrogen energy are methods used to big - scale energy sources.In a mono - phase system with two - step structure if the line voltage is 220 volts, bus inverter voltage that connected to network, should be about 380 volts. However, the output voltage of the photovoltaic cells and fuel cells are generally between 25 to 40 volts this voltage is much lower than the bus voltage. So a high efficiency DC-DC converter output voltage is required to boost fuel cells and photovoltaic cells. In this research, will be presented an improved structure as high efficiency voltage boost converter with a voltage multiplier circuit for solar cell applications. In the proposed structure for efficiency improvement, used voltage multiplier circuit techniques and coupled inductors. We have the proposed converter using the active clamp circuit to achieve soft switching conditions and reduce switching losses. generally, the advantages of the proposed converter are high step-up voltage and high efficiency, low voltage stress for switches and diodes, providing soft switching conditions, and ultimately reducing the number of magnetic elements and the circuit's size. In this paper, in addition to describing the operation of the circuit and provide theoretical analyzes, validity of circuit performance will be evaluated through simulation software
