Non-Isolated High Gain Buck Boost DC-DC Converters Adopting Switched Capacitor Cell for WSN Applications

چکیده
This paper presents a high step up DC-DC converter to boost low voltage PV system voltage. The switched capacitor converter can obtain a high voltage gain but the line and load regulation is poor and the output voltage is not regulated. The output regulation of the non isolated switching mode DC-DC converter is excellent but the voltage gain cannot be too high.A combination method of the SC converter and the switching mode DC-DC converter is proposed. Thus, the voltage gain is increased and decreased by varying the duty cycle of wireless sensor network applications.
