This paper introduces a digitally performed current mode and voltage control for the dc-dc step down converter based on voltage to frequency converter where the average values of inductor current and output voltage are obtained. These current and voltage measurement are realized by the voltage control oscillator (VCO) and counters (digital integrator). Such an approach enables full digitalizati...

The dynamic voltage restorer (DVR) provides a technically advanced and economical solution to voltage-sag problem. As the voltage-restoration process involves real-power injection into the distribution system, the capability of a particular DVR topology, especially for compensating long-duration voltage sags, depends on the energy storage capacity of the DVR. The interline DVR (IDVR) proposed i...

Many claims have been made about the benefits of a current-mode (CM) approach to IC design. The term is used to draw attention to some kind of special dependence on currents as signals, often without a clear orientation to the broader field, referring instead to recent CM papers. Its use suggests a significant and valuable distinction over “conventional” solutions, perhaps in the hope that this...

Wall-surface jet induced by the dielectric barrier discharge (DBD) has been proposed as an actuator for active flow control in aerodynamic applications. Discharge plasma evolution of the DBD plasma actuator was simulated based on a simple fluid model, in which the electron, one type of positive ion and negative ion were taken into account. Two-dimensional simulation was conducted, and the resul...

We investigate the impact of surface defect density on the transport properties of molecular beam epitaxy grown InGaAs/AlInAs Quantum Cascade (QC) structures. We examine six parameters of the current–voltage (IV) characteristics of the QC mesas: turn-on voltage, turn-on current density, turn-on differential resistance, differential resistance, cut-off voltage, and cut-off current density. The a...

Soft Open Points (SOPs) are power electronic devices installed in place of normally-open points in electrical power distribution networks. They are able to provide active power flow control, reactive power compensation and voltage regulation under normal network operating conditions, as well as fast fault isolation and supply restoration under abnormal conditions. Two control modes were develop...

This paper proposes a new control strategy for single-phase voltage source inverters that does not rely on switching based Pulse Width Modulation. The technique is similar to conventional current hysteresis control, but instead of the output current, low-pass-filtered inverter utilised as feedback signal. Nevertheless, instants are determined by predefined band, rather low-cost Complex Programm...

A new fully differential (FD) low input impedance CMOS current buffer with low voltage, and low power operation is presented. The low input impedance is achieved by remarkable reduction of the input node voltage swing using a novel double feedback scheme. Some advantages of the proposed double feedback scheme over the conventional (either positive or negative) feedback techniques are: lower inp...

This paper presents a new mixed-mode (including voltage, current, transadmittance, and transimpedance modes) biquad filter using only two differential voltage current conveyors (DVCCs), two grounded capacitors and three grounded resistors, which are the least number of active components and the minimum number of grounded passive components necessary for realizing current-mode (with high output ...
