Abstract:

The purpose of the article is to obtain a ratio for determining the reactive power of induction motors when powered by semiconductor converters. The task is to determine the dependence of reactive power on control parameters of the converters. The research method used is computer simulation of electric drive based on Fryze power theory for non-sinusoidal currents. The result is the obtained expression for the calculation of reactive power, which takes into account the rated idle current of the motor with sinusoidal power supply and the type of converter, due to introducing special coefficients

Abstract:

Relevance Currently, frequency converters with diode rectifiers are very often used in conveyor drive systems. However, frequency converters generate current harmonics, adversely affecting the quality of the network and the durability of electrical equipment. In the electric drive system, the induction motor consumes the reactive power of the source, which causes losses in the network and reduces the power factor at the input of the converter. Therefore, for the electric drive system, it is necessary to analyze methods for improving the power factor and reducing harmonic distortion of the curr

Abstract:

Globally, the research on electric vehicles (EVs) has become increasingly popular due to their capacity to reduce carbon emissions and global warming impacts. The effectiveness of EVs depends on appropriate functionality and management of battery energy storage. Nevertheless, the battery energy storage in EVs provides an unregulated, unstable power supply and has significant voltage drops. To address these concerns, power electronics converter technology in EVs is necessary to achieve a stable and reliable power transmission. Although various EV converters provide significant contributions, th

A novel battery recharging system for an all-electric driveline comprising a flywheel with a permanent magnet double wound synchronous machine (motor/generator) is presented. The double winding enables two voltage levels and two different power levels. This topology supersedes other all-electric drivelines. The battery operates in a low-power regime supplying the average power whereas the flywheel delivers and absorbs power peaks, which are up to a higher order of magnitude. The topology presents new challenges for the power conversion system, which is the focus of this investigation. The main

Electric propulsion systems for modern civil and military ships, as well as the growing number of electric consumers on board, are a topical issue in terms of onboard electric power quality. In this respect, a growing number of high power static converters are used, which inevitably leads to the appearance, in the electricity distribution network, of voltage and current harmonics with very high weights. Through this work, the authors made a study of these harmonics for two classical cases encountered aboard a ship, namely a nonlinear consumer and a consumer powered by a static six-pulse conver

Moreover, it has an increase in gain that is quadratic of the voltage gain of a standard topology. Also, the suggested converter has a constant current output, which decreases the output voltage ripple and reduces

Traditionally, carrier interleaved technique was used to get lower distorted output voltage, but it gives a higher circulating currents to flow through the Two-VSC‘s. The mutual inductance of the coupled inductors (CI) is utilized for minimizing circulating currents of high frequency components. Nevertheless, CI can‘t have capability to riddle the components generated by low frequency. When these circul
