A DC–DC switching converter chip is proposed to generate both positive and negative voltages for active-matrix LCD (AMLCD) bias. An inductive boost converter and two inverting charge pumps are integrated in a proposed chip by using a 0.5 mm 5 V, 3.5 mm 30 V CMOS process. A conventional scheme used to bias AMLCD employs a switching-boost converter with several off-chip components to generate the...

In this paper, Vienna rectifier and Z Source Inverter (ZSI) based Wind Power Conversion System (WPCS) has been proposed with less number of switches to provide high quality power to off grid system. The three phase full bridge converter has six switches for the conversion of AC-DC and also need separate DC-DC boost converter to boost the DC voltage. In the proposed WPCS, three Phase Vienna rect...

The STATCOM is one of the shunt type FACTS controllers which can supply reactive power and improve bus voltage. STATCOM has advantages like transient free switching and smooth variation of reactive power. This paper deals with the comparison of five level and seven level based STATCOM systems. Usually DC output from the PV source is amplified using a single boost converter. The output of the bo...

Non-linear phenomena occurrence in DC-DC power converters makes them difficult to analyse and to control. We propose to refine the boost converter map-based model by including all converter elements in order to obtain a more accurate model. It is then used to synthesise a fuzzy logic controller ensuring the converter current regulation in wide range of parameters variation and to shift the nonl...

The output voltage obtained from renewable energy sources is low and needs to be stepped up by and order of 20 for practical usage or grid integration.This emphasizes the need for high gain DC-DC converters. The proposed DC-DC converter topology combines the simple boost converter and a coupled inductor with voltage double stages to provide high voltage gain. The main advantages of this topolog...

DC-DC boost converters are mostly employed in renewable energy system such as photovoltaic system, fuel cell and so on, because these systems generate low output voltage which is not suitable for grid connected power applications. This paper proposes an interleaved boost converter which consists of voltage doubler cell and clamped circuit to achieve large output voltage gain without extremely i...

High boost DC/DC voltage conversion is always indispensable in a power electronic interface of certain battery-powered electrical equipment. However, a conventional boost converter works for a wide duty cycle for such high voltage gain, which increases power consumption and has low reliability problems. In order to solve this issue, a new battery-powered combined boost converter with an interle...

Renewable energy sources (RES) place main role in present days to generate power. The Switched Boost Inverter is a single stage dc-ac power converter, whose output voltage can be either greater or less than its input dc voltage. This converter can supply both dc and ac loads, simultaneously, which makes it suitable for micro grid applications. Also, this converter allows shoot-through of the in...
