| چکیده | ||
| In this paper, a high step-up DC-DC converter is proposed for use in photovoltaic systems. In the proposed converter, the interleaving technique is used to reduce the input current ripple. To increase the output voltage gain, a combination of two voltage multipliers is used in the middle part of the converter. Also, because of the low voltage stress of the switches and diodes in the proposed converter, switches with lower conduction resistance and diodes with lower voltage drop can be used to construct the proposed converter to increase the efficiency of the converter. To confirm the operation of the proposed converter, the simulation results with MATLAB software are presented in this paper. A simulated version of the proposed converter can increase the input voltage below about 20 volts to a voltage level of 400 volts. The low voltage stress on semiconductor elements, high voltage gain, and low input current ripple are the critical features of the proposed converter. | ||
