Abstract

The application of a sliding control mode based on a variable structure system (VSS) for an uninterruptable power supply (UPS) is presented. The incorporation of adaptive control facilitates converter operation within a constant commutation frequency, adding an implicit harmonic control to the intrinsic voltage regulation capacity of the VSS systems. The converter is characterized by online generation and good transient performance. The validity of this technique is confirmed by computer simulation. As a consequence of the system's behavior, a minimal-UPS structure is proposed for operation in parallel with the utility grid. The resultant power converter can operate as a reactive power compensator, an energy storage system, and an active filter for the line.<>
具有滑模控制和自适应滞后带的最小UPS结构
提出了一种基于变结构系统(VSS)的滑模控制方法在不间断电源(UPS)中的应用。自适应控制的结合促进了变频器在恒定换相频率内的运行,为VSS系统的固有电压调节能力增加了隐含谐波控制。该变换器具有在线发电和良好的暂态性能。计算机仿真验证了该方法的有效性。作为系统行为的结果,提出了一个最小的ups结构与公用事业并网运行。由此产生的功率变换器可以作为无功补偿器、储能系统和线路的有源滤波器。
