Power supply technology is a basic technology that supports all types of electronic equipment. Switching power supplies, in particular, are characterized by small size, light weight and high efficiency and are the mainstream technology used in power supplies at present. In recent years, with the advent of an advanced information and communications-oriented society, trends toward personalization...

In a photovoltaic system, sun light energy is converted to electricity. The generatedelectricity has a low DC voltage. In order to increase voltage generated by photovoltaic cells (PV),an additive DC-DC converter is required to raise the low voltage to a good level which provides theconditions for connection to DC-DC converters. Low wastes, low costs, and high efficiency are someother specifica...

In this paper, a novel high step-up DC-DC converter is proposed for sustainable energy system. The proposed converter uses coupled inductor and switched-capacitor technique. The capacitors are charged in parallel and are discharged in series by the coupled-inductor to achieve high stepup voltage gain with appropriate duty ratio. Besides, the voltage stress on the main switch are reduced with a ...

A new topology of single-phase two stage AC to DC SEPIC converter in step down configuration with high efficiency at extremely low voltage gain is proposed with high input power factor and low input current total harmonic distortion. In this work, proposal has be given to modify conventional two stage AC to DC SEPIC converter introducing a switched capacitor branch in between the stages. The in...

This paper proposes a new high step-up DC–DC converter designed especially for regulating the dc interface between various micro sources and a dc–ac inverter to electricity grid. The need of Electricity increases the power demand where the power demand met by the conventional sources of energy has some disadvantage of pollution, this disadvantage can be decreased by the use of the Renewable ene...

The design and control of power converters required for DC-DC DC-AC conversions are critical to enhancing durability, reliability, efficiency. interfacing essential conditioning efficient load management. In part 1 this work, a grid supporting control, which makes the photovoltaic-based microgrid operate as current source at same time contribute frequency voltage regulation, is proposed analyse...
