A high power factor and low crest factor Cuk converter for lighting systems
This paper deals with the analysis, design and simulation of power factor corrected (PFC), low crest factor (CF) electronic ballast for a compact fluorescent lamp (CFL). The proposed electronic ballast employs a Cuk buck-boost AC-DC converter as a power factor regulator (PFR) operating in discontinuous conduction mode (DCM). In the proposed electronic ballast, a half bridge series resonant ...

Impacts of dynamic reactive power compensation devices on the performance of wind power generators
This paper investigates the main impacts of dynamic reactive power compensation devices on the performance of induction machine-based wind power generators. The dynamic reactive power compensation devices analysed are the SVC (Static Var Compensator) and the DSTATCOM (Distributed Static Synchronous Compensator). The usage of these devices as a power factor regulator or a voltage regulator is ...

MATLAB-based modelling of Distribution STATCOM applied to isolated power system
This paper presents the modelling of Distribution Static Compensator (D-STATCOM) used in isolated power systems. The model of D-STATCOM is developed using Power System Block-set (PSB) and Simulink toolboxes of standard MATLAB software. Two proportional integral PI controllers are used to control DC bus voltage and AC bus voltage regulation at the point of common coupling. Results are presented ...

Star-hexagon transformer and non-isolated three-leg VSC based three-phase four-wire DSTATCOM
A new three-phase four-wire DSTATCOM (distribution static compensator) is proposed for power quality improvement in the distribution system. The DSTATCOM is based on a star/hexagon transformer and three-leg VSC (voltage source converter). It compensates harmonic current, reactive power and balances the load along with neutral current compensation. Each of the three single phase transformers has ...

Modelling of DSTATCOM for distribution system
This paper deals with the simulation of distribution static synchronous compensator (DSTATCOM) for improving power quality of a distribution system feeding linear as well as non-linear loads. Nowadays, there are an increasing number of non-linear loads which inject harmonics into the system. A three-phase insulated gate bipolar transistor- (IGBT-)based current controlled voltage source inverter ...

Study, modelling and control of a single-phase power factor corrector based on the Sheppard-Taylor topology
In this paper, a single-phase power factor corrector (PFC) based on the Sheppard-Taylor topology is studied. A novel mathematical representation of the converter is elaborated using the state-space averaging technique. In order to emphasise the usefulness of such model, three pulse-width-modulated (PWM) multi-loops control schemes are proposed and developed in the aim of ensuring a unity power ...

New topology for management of bi-directional power flow between vehicle and grid with reduced ripple current at unity power factor
In this paper, a new topology of single-phase pulse width modulated (PWM) AC-DC converter is proposed for bidirectional power flow between plug-in hybrid electric vehicle (PHEV) and the grid. This converter consists of a PWM voltage source converter (VSC) and a ripple reduction circuit. The ripple reduction circuit consists of a switching leg and an inductor. The inductor is connected between ...
