Rectifier circuits make a large number of higher harmonics in the mains and lower the power factor (PF). To reduce this harmful effect, rectifier circuits with electronic control are introduced. This article presents two Power Factor Correction rectifier circuits: I- and 3 -phase circuits. We present here the method of controlling these rectifiers, that allows to increase the power factor of these rectifiers. In the article we present also an algorithms, that provide this controlling The simulation results confirms effectiveness of the proposed controlling. Presented method of controlling of 1- and 3 -phase rectifiers causes, that the current drawn from the main is close to sinusoid and has the same phase as feeding voltage. Computer simulations confirmed effectiveness of the presented controlling So this circuits can be considered as the Power Factor Correction circuits.

Investigation of multilevel inverters for d-statcom applications Deniz, Mustafa; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2009) The most important advantages of Multilevel Inverters are the absence of a coupling transformer for medium voltage applications and low harmonic current content. In this way, relocatable and economical STATCOM systems can be realized. Complex control algorithms and the isolation problems of measurement devices and power supplies are the main challenging parts of this type of application. In this study, the design, realization, and the performance of a Voltage Source Type Cascaded Multilevel Converter Based ...
Frequency Dependent Dielectric Properties of ZnSe/p-Si Diode Güllü, Hasan Hüseyin; YILDIZ, DİLBER ESRA (2019-03-01) The study on electrical and dielectric properties of the ZnSe/p-Si diode have been investigated using admittance measurements in the frequency range of 50 kHz - 1 MHz at room temperature. The experimental values of dielectric constant and dielectric loss are found in decreasing behavior with increase in frequency due to the characteristics of the interface capacitance in the diode and so that the similar behavior was observed in loss tangent. With the contribution of the series resistance, the results of th...
DC-link capacitor sizing of three-level neutral point clamped voltage source inverters for variable speed drives Ogan, Serhat Emir; Bostancı, Emine; Department of Electrical and Electronics Engineering (2021-12-13) A three-level neutral point clamped (NPC) voltage source inverter (VSI) topology can be advantageous in electric vehicles with a high DC-link voltage and a high switching frequency due to the flexibility in power switch selection. However, the potential oscillations in neutral point must be handled to guarantee an efficient operation of this topology. A bulky DC-link capacitor is not an option for EV applications; thus, the sizing of the DC-link capacitor considering the traction system characteristics is a...
Performance optimization of induction motors during voltage-controlled soft starting Zenginobuz, G; Cadirci, I; Ermiş, Muammer; Barlak, C (Institute of Electrical and Electronics Engineers (IEEE), 2004-06-01) This paper deals with the performance optimization of medium/high-power induction motors during soft starting by eliminating the supply frequency torque pulsations, and by keeping the line current constant at the preset value. Starting torque pulsations are eliminated by triggering back-to-back-connected thyristors at proper points on the first supply voltage cycle. Line current during starting can be kept constant at any preset value by a simple strategy composed of successive cosinusoidal and constant fun...
Optimizing transient and filtering performance of a C-type 2nd harmonic power filter by the use of solid-state switches Gerçek, Cem Özgür; Ertaş, Arif; Department of Electrical and Electronics Engineering (2007) In this research work, the performance of a C-type, 2nd harmonic power filter is optimized by the use of a thyristor switched damping resistor. In the design of conventional C-type, 2nd harmonic filters; the resistance of permanently connected damping resistor is to be optimized for minimization of voltage stresses on filter elements arising from switchings in transient state and for maximization of filtering effectiveness in the steady-state. Transformer inrush current during energization of power transfor...
