Special Issue Information

Dear Colleagues,

This Special Issue aims to share the experience of colleagues in the field of power electronics. Here we will consider new solutions in the conversion of AC to DC, DC to AC, AC to AC and DC to DC. Authors will propose new control methods and new circuitry for semiconductor converters.

Both load and energy sources are an integral part of the proposed devices. The application of these devices in renewable energy, electric power generators for mobile vehicles and autonomous objects, electric energy storage devices, drives and electric machines will be considered. In the field of semiconductor converters control, algorithms of digital control systems will be considered, and recommendations will be given for setting up feedback loops for current, voltage, speed, etc. Among semiconductor converters, multipulse rectifier circuits, multilevel inverters, AC voltage regulators, pulse voltage converters, boost, buck, buck–boost and resonant converters will be considered. In addition, circuits of such devices such as matrix converters, cyclo-converters, and frequency converters will be proposed.

The development trends of the modern world of power electronics dictate the requirements for the use of AC voltage converters as soft starters for induction motors. A direct connection of the motors to the mains voltage negatively affects both the motor itself and the mains system as a whole due to high starting currents values, which entail, as a rule, more frequent accidents and shorten the drive system service life. Modern methods of motor acceleration are implemented in practice by means of frequency converters, which require the presence of both a rectifier and an inverter in the structure of the device. The paper presents a study of the control system of a multi-zone AC voltage single-stage regulator. The use of capacitive voltage dividers will also compensate for the consumed reactive power. The article analyzes the features of modern soft starters, describes the circuit design, presents a mathematical calculation by the differential equations algebraization method, a performed simulation modeling in Matlab/Simulink, and also an assembled experimental stand. Particular attention is paid to the definition of the multizonality concept of the proposed converter and the analysis of the control method. The developed algorithm of the double-loop automatic control system will minimize the influence of induction motors on the mains voltage and thus improve electromagnetic compatibility. Full article

Improving the operational reliability of nuclear power plants, combined heat and power plants (CHP), as well as oil and gas pipelines is a priority task in the development of a variable-speed drive for lock valves used at these facilities. This paper analyzes the technical requirements for such devices: the motor has been selected, its electrical equilibrium and moment equations have been obtained; recommendations for the selection of the kinematic drive scheme have been formulated. Based on the theoretical data obtained, a prototype has been developed, manufactured, and tested. Full article
