Voltage multiplier factor circuits area unit wide employed in several high-voltage/low-current applications this paper proposes a hybrid SVM (HSVM) for dc high-voltage applications. The multiplier factor is made by cascading a diode-bridge rectifier associated an (symmetrical voltage multiplier factor) SVM with diode-bridge rectifier because the initial stage of multiplier. The planned topology saves 2 high-voltage capacitors and needs just one secondary of HVT. Besides, it's lesser free fall and quicker transient response at start-up, compared with typical SVM.

This research proposes a change of magnitude dc-dc device supporting the Cockcroft-Walton (CW) voltage number while not a transformer, providing continuous input current, with low ripple, high voltage, quantitative relation and low voltage stress on the switches, diodes, and capacitors. The projected device should be appropriate for applying to low-input-level dc generation systems. In this study, the projected management strategy employs 2 freelance frequencies, one that operates at high frequency to attenuate the scale of the inductance and an opposite one that operates at the comparatively low frequency in keeping with the required output voltage ripple.

Concerns over environment and increased demand of energy have led the world to think about alternate energy sources such as wind, hydro, solar and fuel cells. Out of these, photovoltaic (PV) power generation systems have become increasingly important all over the world due its availability, cleanness, low maintenance cost and inexhaustible nature. But power produced by the photovoltaic system is stochastic in nature due to the variation of solar irradiation and cell temperature throughout the day. In order to track the varying power, a DC-DC converter with maximum power point tracker (MPPT) is used. Different MPPT algorithms have been proposed for tracking peak power from the PV panel. Selection of adequate DC-DC converter is also an important factor since it has an inuence on overall performance of the PV system. This paper presents a comparative study on the characteristics of different non-isolated DC-DC converters and highlights the various research works that has been done on DC-DC converters based MPPT PV system. Study shows that selection of converter also has an impact on the overall performance of the PV system. Based on the survey and comparative study, selection criteria to choose DC-DC converter for PV system is described in this paper. [ABSTRACT FROM AUTHOR]
