Analysis and Design of 3.3 kV IGBT Based Three-Level DC/DC Converter with High-Frequency Isolation and Current Doubler RectifierThe paper presents the findings of a R&D project connected to the development of auxiliary power supply (APS) for the high-voltage DC-fed rolling stock applications. The aim was to design a new-generation power converter utilizing high-voltage IGBT modules, which can outpace the predecessors in terms of power density, i.e. to provide more power for smaller volumetric space. The topology proposed is 3.3 kV IGBT-based three-level neutral point clamped (NPC) half-bridge with high-frequency isolation transformer and current doubler rectifier that fulfils all the targets imposed by the designers. Despite an increased component count the proposed converter is very simple in design and operation. The paper provides an overview of the design with several recommendations and guidelines. Moreover, the simulation and experimental results are discussed and the performance evaluation of the proposed converter is presented.

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.

High-voltage high-frequency power supply using voltage-fed load resonant inverter with a series-compensated resonant inductor has been developed for efficient atmospheric surface glow barrier discharges(ASGBD). It produces a controllable frequency and sinusoidal alternating voltage output. The maximum output voltage is about 6 kV peak to peak. Resonant power converter can be tune easily to the resonant frequency of the load. Operating frequency varies according to the load and voltage level typically in the range of 10 kHz and 1 MHz range. The output voltage is controlled by using pulse width modulation technique. The power supply developed in this paper is applied successfully for ozoniser that can produce high concentrate ozone by using ASGBD for agricultural industry applications.
