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 con...

This paper presents a new step-up DC/DC converter topology to be used for distributed energy systems. The topology contains a voltage-fed quasiZ-source inverter with continuous input current, a high-frequency step-up isolation transformer and a voltage doubler rectifier. Main operating modes of the converter are explained and steady state analysis of the voltage-fed quasi-Z-source inverter is p...

A unified multi-stage power-CMOS-transmission-gate-based quasi-switched-capacitor (QSC) DC-DC converter is proposed to integrate both step-down and step-up modes all in one circuit configuration for low-power applications. In this paper, by using power CMOS transmission gate as a bi-directional switch, the various topologies for step-down and step-up modes can be integrated in the same circuit ...

In this project photovoltaic array is used as source. The photovoltaic energy is used to feed the inverter through the step up converter. The output for solar module is connected to the battery. So the supply is given continuously by the battery to the system. The output of the solar may vary due to the radiation and will affect the battery. So the lifetime of battery is reduced. It is necessar...

In this paper, analysis, design and implementation of non-isolated soft-switching bidirectional DCDC converter with an active switch are described. The proposed topology gives the output voltage as twice as the input voltage and enhances the efficiency up to 94.5% and 92.9% for boost and buck mode operation by proper selection of the duty cycle. Soft switching can be achieved at both steps up a...
