In this paper, a real-time demodulation of real power oscillations in a three phase electric power system is proposed. It is shown how demodulated real power oscillations can be used to formulate a low order state space model that models power oscillations. The procedure is illustrated on the measurements obtained from three phase Resistor-Inductor-Capacitor (RLC) network where the power oscill...

This paper summarizes recently developed soft-switching inverters and proposes two alternative options for electric propulsion drives. The newly developed soft-switching inverter employs an auxiliary switch and a resonant inductor per phase to produce a zero voltage across the main switch so that the main switch can turn on at the zero-voltage condition. Both the auxiliary switch and the resona...

This research presents a non-isolated multi-port power converter feasible to hybridize energy alternatives in electric vehicles. Due the hybridization of various input sources, there are several advantages load distribution system. Flexible control discharging as well charging process concerning sources can be achieved. The developed able boost voltage levels with dual inputs such renewable sol...

Metal Halide High Intensity Discharge lamps are becoming popular because of its high efficacy. The operating characteristic of Metal Halide High Intensity Discharge (HID) lamps is complex as it has several stage of operation. So electric control system is required to control the operation of metal halide high intensity discharge lamps. Electric control system involves a number of non linear dev...

Printing functional materials represents a considerable impact on the access to manufacturing technology. In this paper we present a methodology and validation of print-and-self-fold miniature electric devices. Polyvinyl chloride laminated sheets based on metalized polyester film show reliable self-folding processes under a heat application, and it configures 3D electric devices. We exemplify t...

A new method for predicting the stray capacitance of inductors is presented. The method is based on an analytical approach and the physical structure of inductors. The inductor winding is partitioned into basic cells—many of which are identical. An expression for the equivalent capacitance of the basic cell is derived. Using this expression, the stray capacitance is found for both singleand mul...

In recent years there has been much interest in the nature of two stars, V407 Vul and RX J0806+1527, which are widely thought to be binary white dwarfs of very short orbital period, 570 and 321 seconds respectively. As such they should be strong sources of gravitational waves and possible ancestors of the accreting AM CVn stars. Monitoring at X-ray and optical wavelengths has established that t...
