提出了一种能够补偿临界负载端电压谐波和电压调节的单相交-交矩阵变流器。该变流器由最少的开关器件组成，采用基于无源的非线性控制方法，在暂态和稳态运行条件下具有较高的可靠性和鲁棒性。所提出的方案具有不需要储能装置的优点。变流器通过串联变压器连接在交流电源和负载之间。利用数字信号处理器(DSP)和现场可编程门阵列(FPGA)分别对无源控制器进行编程，并确定开关的状态。在这种情况下，变流器能够补偿高达25%的电压凹陷和50%的电压上升，并消除高达15次的谐波分量。被测系统具有较快的时间响应，负载电压稳定时间小于1ms。分析和给出了一个5kVA、127V、60赫兹的实验装置的分析和建模以及仿真和实验结果
This paper presents a single-phase AC-AC matrix converter which is able to compensate voltage harmonics and voltage regulation at critical loads terminals. The converter is composed with the minimum number of switching devices and is controlled using a non-linear law based on passivity achieving a high reliability and robustness during transient and steady state operation condition. The proposed scheme has the advantage that energy storage devices are not required. The converter is connected between the AC mains and the load through a series transformer. A DSP and a FPGA are used to program the passivity-based controller and to determine the state of the switches respectively. In this case, the converter is able to compensate up to 25% voltage sags and 50% voltage swells and to eliminate up to the fifteenth harmonic component. The tested system presents a fast time response and the stabilization time of the load voltage is less than 1 ms. Analysis and modeling as well as simulation and experimental results of a 5 kVA, 127 V, 60 Hz experimental setup are analyzed and presented
