A gyrator design based on an inductor coupled double bridge converter is presented. It is shown that this gyrator can operate in four-quadrant mode by using bi-directional MOS switches without the necessity of any feedback control circuit. There are different usage areas of such a gyrator. Some of which can be used for conversions of voltage to cur...

A useful technique to multiply the frequency of an input square wave by n times without losing synchronization with an original waveform is proposed. A circuit which implements this technique for f = 50 Hz and n = 12 is described and experimental results are given.
This paper describes a study on a well studied subject, driving 3-phase induction motor. But the hardware used for the study is different than the conventional 16-bit microcontrollers or DSPs. The aim of the project is to lower the price of control hardware and achieve a satisfying performance with less expensive 8-bit microcontrollers.
This paper presents torque ripple minimization of a switched reluctance motor (SRM) by using a fuzzy controller, The nonlinear model of the SRM and the mathematical model of the converter circuit are driven. The motor used in both simulation and experiment is an 8/6 four phase SRM with a C-Dump converter. The applied fuzzy controller adjusts the va...
This paper presents torque ripple reduction of Switched Reluctance Motor (SRM) by using fuzzy speed controller. In this purpose, current control is applied with fuzzy speed controller. Fuzzy controller adjusts value of reference current to keep speed constant. In this study, the nonlinear model of SRM is used and the motor used in simulation is a 8...
Electric power generation and conditioning have experienced
revolutionary development over the past two decades. Furthermore, new
materials such as high energy magnets and high temperature
superconductors are either available or on the horizon. Our work is
based on the premise that new technologies are an important driver of
new power system concep...
A new approach to superconductive magnetic energy storage (SMES)
for solar power satellite (SPS) with inherent rigidity is introduced in
this paper. The rigidity of this SMES originating from the
electromagnetic forces within it, can eliminate the need for mechanical
building blocks for support structure. This force can also be used for
the deploym...
The bang-bang controlled capacitor coupled converter
(C<sup>3</sup>) is described in this paper. Due to the converter's
inherent commutating property, the C<sup>3</sup> can accommodate
thyristors as well as high-power gate turn-off switches, due to
zero-current switching transitions. The zero-current switching is
achieved at no current stress incre...
This paper presents a simple technique to minimize torque ripple
of a switched reluctance motor. The technique is based on the control of
the sum of the square of the phase currents by using only two current
sensors and analog multipliers. The simulation results and a proposed
circuit are given. The advantages and its limitations of the proposed
ci...
The authors investigate the open-loop gyrator behavior of a class
of DC-DC converters that are characterized by double bridges. If the
switching frequency of the double bridge converter is high enough with
respect to its natural frequencies, the converter can be viewed as a
gyrator from its terminals. Unlike other gyrator modeling approaches for
co...
A family of DC-DC converters suitable for high-power applications
is introduced. The inverse dual converter (IDC) is capable of continuous
voltage step-up or step-down control over a wide range of and without
the need of a transformer. Experimental verification of the analysis is
given for the simple single-phase IDC. Some of the more sophisticated...
The capacitive coupled converter for high-power voltage source
DC-DC applications is described. Its steady-state and dynamic behavior
are analyzed theoretically and by computer simulation. Factors affecting
its operation and control are discussed and some design rules are
presented. A proof-of-principle model of the capacitive coupled
converter was...
DC to DC power converter topologies that are suitable for high-density, high-power supplies are presented. Topological variations on the basic inverse dual converter (IDC) circuit, such as the coupled transformer and the multiphase and multipulse derivation of the single-phase IDC, are analyzed, and simulation results are discussed. The topologies...
The single flying capacitor converter (SFCC) is a two-quadrant
power supply for energy storage and transfer system. It has applications
in nuclear research and pulsed power systems in which superconductive
coils are used in superconductive magnets. The authors derive analytical
expressions for the time-averaged behavior of the SFCC by using the
sta...
The time-averaged behavior of an inductor-converter bridge (ICB) circuit has been analyzed using a state-space averaging technique. The application of the state-space averaging technique to the ICB circuit analysis is somewhat different from the well known DC-to-DC converter cases such as buck, boost, and flyback of Cuk converter analysis in that t...
