Abstract:

Introduction. Linear pulse electromechanical converters of induction type (LPECIT) are used in many branches of science and technology as shock-power devices and electromechanical accelerators. In them, due to the phase shift between the excitation current in the inductor winding and the induced current in the armature winding, in addition to the initial electrodynamic forces (EDF) of repulsion, subsequent EDF of attraction also arise. As a result, the operating indicators of LPECIT are reduced. The purpose of the article is to increase the performance of linear pulse electromechanical inducti

The purpose of the article is to evaluate the efficiency of an induction-type linear pulse electromechanical converter (LPEC) when operating in shock-power mode and excitation from an alternating voltage source (AVS) in comparison with excitation from a capacitive energy storage (CES). A mathematical model of an induction-type LPEC has been developed both when excited by a unipolar pulse from a CES and from an AVS using lumped parameters of the windings, which takes into account the interrelated electromagnetic, mechanical and thermal processes. It has been found that when the LPEC is excited

Abstract:

The stepper motor is an electromechanical converter that transforms a pulsed electrical signal into a mechanical movement (angular or linear). Its basic structure is in the form of two mechanically separated parts, the stator and the rotor. The electromagnetic interaction between these two parts ensures rotation. In the design of automatic systems, one always seeks to improve the dynamic performances and to minimize the response time. Conventional control algorithms, for example, with integral proportional action, may be sufficient if the requirements on the accuracy and performance of the sys

Modeling of electrical complexes, which include semiconductor converters together with electromechanical, thermodynamic and other relatively slow processes, is faces the problem of a significant increase in simulation time. One way to solve this problem is to use the mathematical description of the semiconductor converter in the values a

Abstract:

The article proposes a solution to the problem of optimizing the magnetic system design of a low-speed synchronous motor with permanent magnets (PMSM) as a part of a linear drive of a single-stage piston compressor that is promising for use in compressor construction for a given law of motion of the moving part. The maximum efficiency of the electromechanical converter is used as an optimality criterion. By solving the optimization problem, the relationship between the design parameters and the energy performance of the PMSM was established in an analytical form. The substantiation of the maxi

The issues of constructing mathematical models for systems that, in addition to the object, include a power converter, a measuring system and an on-board computer are considered. The last three elements are united by a single concept – «device». It is shown that the newly obtained «device–object» system, under certain conditions, should be considered and described as a single whole when solving problems of identification and control. Using a heuristic method, mathematical models of the «device–object» system are constructed and justified, in particular, the system of exchange equations, the ex

AbstractThe purpose of scientific research in this paper is to improve the operation of thermal power plants. The experimental stand for the study was made for testing, verifying and adjusting the dynamic parameters of the electromechanical actuators that are integrated in the gas valve component. In order to improve the performance of the thermal power plants by increasing the energetic, mechanical, electrical efficiency, this will be achieved through an alternating-alternative static converter, experimentally realizing the single-phase alternating voltage variable module.

A three-phase silicon controlled rectifier converter with adjustable firing angle connected to the load has formed the variable non-linear component.

Abstract This paper presents a zero-voltage-switching (ZVS) full-bridge based DC-DC converter with linear voltage gain according to duty cycle. The proposed converter is based on an asymmetrical pulse-width-modulation (APWM) full-bridge converter which has various advantages over other converters. However, it has some drawbacks such as limited maximum duty cycle to 0.5 and narrow input range. The proposed converter overcomes these problems. The duty cycle is not limited and input voltage range is wide. Also, the ZVS operation of all power switches is achieved. Therefore, switching losses are s

Abstract:

Sinusoidal pulse width modulation (SPWM) is a method to generate the switching gate pulse of the converter. Overmodulation is a method where the modulation index exceeds the unity value and the system goes into the nonlinear region. To maintain the system in a linear region when operating in the overmodulation region, some techniques are developed. These techniques helped to operate the system in the linear range. Medium and high-power energy conversion systems mostly use a modular multilevel cascaded converter (MMCC), which has been an issue improving significantly in recent years. In this ar
