A frequency tunable resonator topology is proposed that consists of an S-shaped resonator, a ground frame and a feeding transmission line. Tunability is achieved by using reverse biased varactor diodes employed at critical locations on the structure. As well as being a tunable resonator, the structure also provides tunable metamaterial properties. Reflection and transmission parameters, electric and magnetic field distributions, and permittivity and permeability at each tuned frequency were analyzed and shown. Simulation and measured results agree well and demonstrate about 28% frequency tunability.

A Tunable Metamaterial Resonator Using Varactor Diodes to Facilitate the Design of Reconfigurable Microwave Circuits
Nesimoglu, Tayfun; Sabah, Cumali (2016-01-01)
In this brief, we designed, constructed, and analyzed a frequency-tunable metamaterial resonator. The proposed design consists of an S-shaped resonator, a ground frame, and a feeding transmission line. First, the structure is designed as a nontunable resonator and then tunability is achieved by employing varactor diodes. In order to verify and demonstrate its tunable metamaterial properties, reflection and transmission parameters, group delay, electric and magnetic field distributions, and permittivity and ...
A Near-State PWM Method With Reduced Switching Losses and Reduced Common-Mode Voltage for Three-Phase Voltage Source Inverters
Uen, Emre; Hava, Ahmet Masum (2009-03-01)
The near-state pulsewidth modulation (NSPWM) method, which reduces the common-mode voltage/current, is proposed for three-phase pulsewidth modulation (PWM) inverter drives. The method is described, its optimal voltage vectors are found, and the sequence that these vectors are applied is determined. Its voltage linearity and de bus and ac output PWM current ripple characteristics are studied. Its output line-to-line voltage pattern is carefully studied with regard to switching transients that may cause overv...
A DRBEM solution for MHD pipe flow in a conducting medium
Han Aydın, S.; Tezer, Münevver (Elsevier BV, 2014-3)
Numerical solutions are given for magnetohydrodynamic (MHD) pipe flow under the influence of a transverse magnetic field when the outside medium is also electrically conducting. Convection-diffusion-type MHD equations for inside the pipe are coupled with the Laplace equation defined in the exterior region, and the continuity requirements for the induced magnetic fields are also coupled on the pipe wall. The most general problem of a conducting pipe wall with thickness, which also has magnetic induction gene...
A Near State PWM Method With Reduced Switching Frequency And Reduced Common Mode Voltage For Three-Phase Voltage Source Inverters
Un, Emre; Hava, Ahmet Masum (2007-05-05)
The Near State PWM (NSPWM) method, which reduces the common mode voltage/current, is proposed for three-phase PWM inverter drives. The optimal voltage vectors and their sequences are determined. The voltage linearity and DC bus and AC output PWM current ripple characteristics are studied. The method is thoroughly investigated and its performance is compared to conventional methods. Theory, simulations, and experiments show that NSPWM exhibits superior common mode and satisfactory PWM ripple performance char...
A Parabolic Band Hysteresis Current Controller for Doubly Fed Induction Generators
Hamadi, Emad; Mortazavi, S. S. (2011-09-10)
A parabolic band hysteresis current controller (PBHCC) for DFIG is proposed in this paper to control the switching frequency variations in rotor side converter (RSC). A generalized online technique is used to determine the set of unique parabolic boundary for any operation speed. The PIHICC then utilized to regulate the current in RSC. In contrast to PI controller, PBHCC shows a very good transient behaviour. Beside that, the steady state performance is improved by reducing the switching frequency considera...
