چکیده انگلیسی
The objective of this work is to achieve high step-up voltage gain with appropriate duty ratio with the application of cascode technique on buck boost converters for electric energy conversion system. As the available electrical AC voltage cannot be directly fed to electronic power devices, these devices and load require DC Power conversion from AC voltage sources. Conventional boost converters are unable to provide high voltage gains due to the effect of power switches, the impact of the parasitic resistive components and the reverse-recovery problem of the diodes. In this paper high voltage gain step-up (HVGSU) DC-DC converter is proposed, which consists of two integrated buck-boost converters with a single switch. High voltage gain can be achieved using cascode technique without any extreme duty ratio, here the duty ratio of the switch is controlled using PWM technique. The simulation and hardware of the proposed converter is discussed in detail.
