The efficient and fast control of electric power forms part of the key technologies of modern automated production. It is performed using electronic power converters. The converters transfer energy from a source to a controlled process in a quantized fashion, using semiconductor switches which are turned on and off at fast repetition rates. The algorithms which generate the switching functions ...

The objective of this paper is present the data requirements for modeling power electronic devices to aid in modeling power converters for transient simulation studies. The presentation will target applications of power semiconductor devices commonly used in medium to high power applications: insulated gate bipolar transistors (IGBTs), Thyristors (SCR), and Gate TurnOff Thyristors (GTOs) and po...

The selection of control strategy depends on the converters of the drive including power, speed, performance and the possible system costs. A number of attempts were therefore made in recent times to develop novel power electronic converter structures for SRM drives, based on the utilization. Many of the converters with variable speed drives have no input power factor correction circuits. This ...

High-speed and high-resolution analog-to-digital converters (ADC) are critical devices for space electronic systems. Analog Devices’s bipolar technology 12-bit A/D converter, AD574A, was proven to withstand up to 100 krad(Si) [1], but excessive power consumption limits its applications in many new high-speed and low-power system designs. Several other commercial 12-bit successive approximation ...

Advances in power electronics enable efficient and flexible interconnection of renewable sources, loads and electric grids. While targets concerning efficiency of power converters are within reach, recent research endeavors to predict and improve their reliability to ensure high availability, low maintenance costs, and therefore, low Levelized-Cost-of-Energy (LCOE) of renewable energy systems. ...

In industrial electronic systems, power converters with power components are used. Each controlled component has its own control circuit. In this paper, the authors propose an original control circuit in order to replace the different existing circuits. The proposed circuit is the representation of an elliptical trigonometry function. Thus, by varying the value of one of its parameter, the outp...

This article aims to incorporate the reliability model of power electronic converters into system analysis. The converter has widely been explored in device- and converter-levels according physics failure However, optimal decision-making for design, planning, operation, maintenance require system-level modeling electronic-based systems. Therefore, this proposes a procedure evaluate systems from...
