The era of evolution in power electronic systems has led to a widespread displacement of power supplies operating at mains frequencies. Switched-mode power inverters offer possibilities incomparably higher than mains transformers. These trends have also entered into plasma technologies, including GlidArc plasma processing. The article presents the use of an inverter power supply for a miniaturized GlidArc. It is a demonstration of using a push–pull topology in an unusual application. A special part is devoted to parasitic phenomena in the inverter and the implementation of switching overvoltages as a way of improving the ignition parameters of the power supply. The results of the tests with a plasma reactor in air conditions as a process gas are also presented.

The scientific objective was to investigate the cooperation of three-electrode plasma reactors with gliding arc discharge powered from multi-phase AC/DC/AC converters. In order to achieve the scientific and practical goal of the project, a test stand was designed and built, which included: a multi-electrode GlidArc type plasma reactor; a power-electronic AC/DC/AC converter, working as a source of voltage or current with regulated parameters of energy transferred to the discharge space; reactor operation diagnostics systems; and a process gas feeding and flow control system. The GlidArc Plasma Reactor has shown high sensitivity to changes in many electrical as well as gas chemical, gas-dynamic and mechanical parameters. The AC/DC/AC converter turned out to be a system sensitive to interference generated by the plasma reactor. It can be noticed that the operation of the reactor in certain conditions causes bigger interferences of the converter. However, it is difficult to systematise the influence of particular parameters of the reactor’s operation on the operation of the AC/DC/AC converter and vice versa due to mutual correlations of many parameters. The correct operation of a plasma reactor depends on the characteristics of the power supply system; on the other hand, the power supply system reacts to such an untypical receiver as a plasma reactor.

The paper provides the results of experimental study of how the technological characteristics (amount of spatter, stability of the welding process) of manual metal arc welding (MMA) depend upon power supplies providing various kinds of energetic impact upon the electrode metal (inverter power supply, diode rectifier). It was established that inverter power supplies (as they reduce peak loading) provide better quality of welds (more stable process, lower amount of spatter) and this reduces the fabrication cost due to the reduction of deseaming operations, lower welding material consumption as well as improving the service reliability of the welding constructions.

Overvoltage Protection

An attempt is made for simplifying the circuit structure of the surge protective device (SPD) installed on single-phase AC power supply lines of electronic systems. In the light of the drawback of the traditional circuit, a simplified circuit is proposed. The simplified circuit can substantially reduce the number of the protective components and the size of the SPD chassis. In order to compare the protective performances between the traditional and simplified circuits, an impulse experimental arrangement is built to measure their residual voltages. The measured results show that the voltage protection level of the simplified circuit is the same as that of the traditional circuit. Therefore, replacement of the traditional circuit by the simplified circuit is really feasible in lightning overvoltage protection of AC power supplies of electronic systems.

Distributed Power

In distribution networks with distributed power supplies, distributed power supplies can also be used as backup power sources to support the grid. If a distribution network contains multiple distributed power sources, the distribution network becomes a complex power grid with multiple power supplies. When a short-circuit fault occurs at a certain point on the power distribution network, the size, direction and duration of the short-circuit current are no longer single due to the existence of distributed power, and will vary with the location and capacity of the distributed power supply system. The change, in turn, affects the current in the grid, resulting in the generation and propagation of additional current. This power grid of power electronics will cause problems such as excessive standard mis-operation, abnormal heating of the converter and component burnout, and communication system failure. It is of great and practical significance to study the influence of distributed power in distributed power distribution networks.

Gate Drivers

This thesis is devoted to the development of a novel parallel isolated power supply (PIPS) for the gate driver of integrated Gate Commutated Thyristors (GCT). The proposed PIPS is essentially a special high frequency soft switched DC/DC converter, integrating six parallel isolated power supplies in one module where each power supply generates a regulated dc supply for the GCT gate driver. In commercial GCT power supplies, a high-voltage isolation transformer is indispensable but highly inefficient in terms of cost and size, which can be significantly improved by the optimized transformer. In all, this design strives to achieve a general power supply for powering up the gate drivers of all types of GCT devices in all MV applications with minimal changes in configuration. In this thesis, the configuration of PIPS is presented and its operating principle is elaborated. The transformer optimization procedure satisfying the voltage isolation requirement of GCT gate drivers is extensively discussed. The performance of PIPS, including the front end DC/DC converter, zero voltage switching phase-shift full bridge (ZVS-PS-FB) converter, and the optimization of the transformer, is verified by simulations and experiments where a 360W laboratory prototype is built for the experimental use.
