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 variable frequency sine wave output buck-boost inverter
Şener, Yunus; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2016)
Conventional inverters have pulse-width-modulated output with a fundamental component at the desired frequency and magnitude. These converters are usually buck type and therefore the DC link voltage limits the maximum 3-phase output voltage magnitude. As a consequence, in motor drive applications field weakening is essential after a certain frequency of operation, as it becomes impossible to preserve the rated flux level. In renewable energy applications similar problems arise. When the DC link voltage fall...
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...

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...

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...
