In this work, the operating modes and characteristics of a Z-source full-bridge dc/dc converter are investigated. The mathematical analysis of the converter in continuous conduction mode, CCM and discontinuous conduction mode-2, DCM-2 operations is conducted. The transfer functions are derived for CCM and DCM-2 operation and validated by the simulation. The current mode controller of the converter is designed and its performance is checked in the simulation. The component waveforms in CCM and DCM-2 modes of operation are verified by operating the prototype converter in open-loop mode. The designed controller performance is tested with the closed-loop control implementation of the prototype converter. The theoretical efficiency analysis of the converter is made and compared with the measured efficiency of converter.

Design and implementation of coupled inductor Cuk converter operating in continuous conduction mode
Ayhan, Mustafa Tufan; Ersak, Aydın; Department of Electrical and Electronics Engineering (2011)
The study involves the following stages: First, coupled-inductor and integrated magnetic structure used in Cuk converter circuit topologies are analyzed and the necessary information about these elements in circuit design is gathered. Also, benefits of using these magnetic elements are presented. Secondly; steady-state model, dynamic model and transfer functions of coupled-inductor Cuk converter topology are obtained via state-space averaging method. Third stage deals with determining the design criteria to...
Design and implementation of an unregulated DC-DC transformer module using LLC resonant converter
Alemdar, Öztürk Şahin; Keysan, Ozan; Department of Electrical and Electronics Engineering (2016)
A traditional high-power front-end DC-DC converter can be replaced with an array of paralleled standardized converter modules when modular design is applied. Modular front-end DC-DC converters represent many desirable properties such as expandability of output power capacity, redundancy implementation, simplified thermal management, and reduced design cost. However, in order to benefit from modular design, load current sharing must be accomplished among the paralleled modules. In this thesis, an LLC resonan...
Design and Analysis of Frequency-Tunable Amplifiers using Varactor Diode Topologies
Nesimoglu, Tayfun (Springer Science and Business Media LLC, 2011-08-01)
The design of frequency-tunable amplifiers is investigated and the trade-off between linearity, efficiency and tunability is revealed. Several tunable amplifiers using various varactor diode topologies as tunable devices are designed by using load-pull techniques and their performances are compared. The amplifier using anti-series distortion-free varactor stack topology achieves 38% power added efficiency and it may be tuned from 1.74 to 2.36 GHz (about 35% tunable range). The amplifier using anti-series/an...
Calculation of core losses of a six-phase induction motor with third harmonic current injection
Büyükbaş, Afşin; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2004)
The advantages of using a six-phase induction motor for industrial drives, over the conventional three-phase drive can be summarized as improved reliability, reduction on the power ratings for the static converters and harmonic reduction. A technique of injecting third harmonic zero sequence current components in the phase currents to improve the machine torque density was presented recently by another research study. However, to meaninigfully evaluate the performnce of such machines and/or to be able to ma...
Design and implementation of a voltage source converter based statcom for reactive power compensation and harmonic filtering
Çetin, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007)
In this thesis, design and implementation of a distribution-type, voltage source converter (VSC) based static synchronous compensator (D-STATCOM) having the simplest converter and coupling transformer topologies have been carried out. The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
