Abstract: In this paper, a non-isolated DC-DC boost converter with high voltage gain and low voltage stress across semiconductors is presented as suitable for PV applications. The proposed converter used voltage multiplier techniques diode/capacitor (D-C) for increasing the output voltage level. The main advantages of the proposed converter include low input current ripples, low voltage stress across semiconductor (power switch and power diodes), high overall efficiency and low conduction losses. Moreover, the proposed converter is capable of achieving maximum power by controlling the duty cycle values. The laboratory prototype of the proposed converter is built and tested at 33 kHz with about 155 W power levels. Both simulation and experimental results confirm the validity of the proposed converter.

Keywords: DC-DC non-isolated converter; high voltage gain; voltage stress; renewable applications; maximum power point tracking.
