Abstract: Harmonic pollution and low power factor in power systems caused by power converters have been of great concern. To overcome these problems several converter topologies using advanced semiconductor devices and control schemes have been proposed. In this paper a new three-level ac–dc single-stage converter that can operate with standard phase-shift pulse width modulation is proposed.The...

Most of the power electronic equipments are operated with dc supply. For reliable and stable operation, dc supply should be regulated. The regulation can be performed using buck, boost, Cûk, Sepic, Flyback regulators. Except single phase rectifier with resistive load all other rectifiers input currents are non sinusoidal in nature. This front end current distortion of rectifier converter leads ...

This paper presents the design and implementation of a power converter for an autonomous wind induction generator (IG) feeding an isolated load through the PWM-based novel soft-switching interleaved boost converter. The output voltage and frequency of the wind IG is inherently variable due to random fluctuation of wind-speed variation. The interleaved boost converter composed of two shunted ele...

This paper is about the implementation of SEPIC Converter and Induction Motor fed water pumpanalysis to improve the efficiency of the input and it act as a impedance matching network. SEPIC Converter is a newly invented chopper in which it has less no components. So, switches losses and conduction losses are reduced in turn it improves the efficiency and reduce the harmonics. When internal impe...

The use of wind turbines is increasing at very high rates in many countries around the world. Studies to evaluate the impact of connecting these new generation units to the existing power systems must be done. This paper proposes a wind energy conversion system for a grid connected permanent magnet synchronous generator (PMSG) and power electronic converter system. The model includes a PMSG mod...

An extension of the one-cycle control (OCC) method for switched-capacitor (SC) converters is proposed in this paper, featuring a fast dynamic response, wide line and load operation ranges, and simplicity in implementation. To illustrate the operation principle of this nonlinear control method and to demonstrate its simplicity in design, a dual-phase unity gain SC converter is examined. A new co...

. Abstract: This paper presents a Fuzzy sliding mode controller (FSMC) used as a control technique for a Single phase AC/DC boost PFC converter for achieving high power factor and regulated voltage. The controller possesses the merits of both fuzzy controller and variable structure controller. The considered controller has advantages such as robustness when there is a large line and load variat...

This Paper focused on Buck/Boost Rectification by Single Phase Matrix Converter with fewer numbers of switches. The conventional matrix converter consists of 4 bidirectional switches, i.e. 8 set of IGBT/MOSFET with anti parallel diodes. In this proposed matrix converter, only six switches are used. The switch commutation arrangements are also carried out in this work. The gate pulses to the swi...
