Increased automation in the manufacturing process has spurred considerable research interest in the next generation of solid state power converters. These converters are expected to be rugged, cheap and compact. These requirements cannot be satisfied by existing converters because of bulky L-C components and their inability to operate under all operating conditions. Recent research on Matrix Converters, PWM inverters and PWM rectifiers has shown the following advantages: complete absence of dc link components (for matrix type); compact, light in weight, and the ability to integrate along with heat sink; the possibility of bi- directional power flow and low distortion input current. In spite of the enormous application potential of these converters, and the availability of new power semiconductor devices such as MCT's, further development and application has been relatively stalled. This is due to the following reasons: high converter performance claims are valid only for ideal operating conditions such as when the input supply is balanced and the output load is linear and balanced. An important list of unknowns for the converters are: Matrix and ac to dc converter input output behavior is very sensitive for the unbalances in input supply and their effects are unknown; PWM inverter behavior in the presence of dc-link voltage ripple is also unknown. Therefore, for the next generation converters to be rugged, small in size and high in performance the effects of unbalances must be first evaluated and some novel power control strategies to guard against these imperfections must be explored. The aim of this research is to address these issues and systematically evaluate the converter behavior via mathematical modeling and provide answers to the above listed unknowns. Some novel power control strategies to correct for unbalanced operation and methods to reject dc-link voltage ripple are proposed. Finally, design guides for practical realization of the proposed strategies via digital signal processing hardware are examined. The success of this research will be a major contribution towards a full scale practical realization of next generation static power converters.

制造过程自动化程度的提高， 对下一代固态技术的研究兴趣很大 电源转换器 这些转换器预计将坚固耐用， 和紧凑。 这些要求不能通过现有的 转换器，因为庞大的L-C组件和他们无法 在所有操作条件下运行。 矩阵变换器、PWM逆变器和PWM整流器的研究进展 已经显示出以下优点：完全没有直流链路 组件（用于矩阵型）;结构紧凑，重量轻， 与散热器集成的能力;双 定向功率流和低失真输入电流。 尽管这些转换器具有巨大的应用潜力， 以及诸如MCT的新功率半导体器件的可用性， 进一步的开发和应用相对停滞。 这 是由于以下原因：高转换器性能要求 仅在理想的操作条件下有效，例如当输入 电源是平衡的，输出负载是线性和平衡的。 一个 转换器的未知数的重要列表是：矩阵和交流到 直流转换器的输入输出行为对 输入电源不平衡及其影响未知; PWM逆变器 在存在DC链路电压涟漪时的行为也是未知的。 因此，下一代转换器必须坚固耐用、体积小， 规模和高性能的不平衡的影响必须首先 评估和一些新的功率控制策略，以防止 这些缺陷必须加以探讨。 本研究的目的是系统地解决这些问题， 通过数学建模评估转换器行为，并提供 对上面列出的未知数的回答。 一些新颖的功率控制 纠正不平衡操作的策略和拒绝方法 DC链路电压涟漪。 最后， 通过数字信号实际实现所提出的策略 检查处理硬件。 这项研究的成功将 是对全面切实实现 下一代静态功率转换器。
