1. Producing of active filter with compensation for unbalanced three-phase voltagesAn of active filter with compensation for unbalanced three-phase voltages was produced. This system mainly consists of two circuits. One is an active filter circuit to compensate for current harmonics and the other is a compensator for unbalanced three-phase voltages. The former circuit is operated to synthesize currents which are antiphase with the load harmonic currents and the latter is operated to synthesize voltages which are antiphase with the negative sequence voltages of the source voltages.Thses circuits have only one energy storage capacitor in common. Therefore, this system needs lower capacity of the energy storage capacitor in comparison with other system which an active filter and an unbalanced voltage compensator are operated independently. In other words, we can make our active filter system compact.2. Steady state analysis of active filter circuitA set of 19 simultaneous differential cqu … More ations for an active filter circuit was derived and various waveforms of currents were calculated. The analytic results coincided with the experimental. Next, a passive filter to suppress the harmonic current generated by the PWM inverter of the active filter was designed with the analytic results. On basis of the analytic results, an active filter circuit with double current loops was proposed. By using these double current loops, both response of current control and stability of the system can be improved.3. Steady state analysis of active filter with compensation for unbalanced three-phase voltagesIn addition to the 19 differential equations in the section 2. , new 13 differential equations for the unbalanced voltage compensator were derived and various waveforms of both currents and voltages were calculated. The analytic results coincided with the experimental. In both analytic and experimental results, improvement in THD for the source corrents and in unbalance of the three-phase voltages was shown. Consequently, the availability of the proposed system was indicated. Less

1.三相电压不平衡补偿有源滤波器的研制提出了一种三相电压不平衡补偿有源滤波器。该系统主要由两个电路组成。一个是补偿电流谐波的有源滤波器电路，另一个是三相电压不平衡的补偿器。前一种电路用于合成与负载谐波电流反相的电流，后一种电路用于合成与电源电压负序电压反相的电压，这两种电路共用一个储能电容。因此，与有源滤波器和不平衡电压补偿器独立操作的其他系统相比，该系统需要更低容量的能量存储电容器。换句话说，我们可以使我们的有源滤波器系统紧凑。有源滤波电路的稳态分析一组19个同时微分电路 ...更多信息 导出了有源滤波电路的计算公式，并计算了各种电流波形。分析结果与实验结果相吻合。其次，根据分析结果设计了一种无源滤波器，用于抑制有源滤波器PWM逆变器产生的谐波电流。在此基础上，提出了一种双电流环有源滤波电路。通过采用双电流环，提高了电流控制的响应速度和系统的稳定性.具有不平衡三相电压补偿的有源滤波器的稳态分析除了第2节中的19个微分方程之外。推导了新的13个不平衡电压补偿器微分方程，计算了各种电流和电压波形。分析结果与实验结果相吻合。在分析和实验结果中，改善了THD的源电流和三相电压的不平衡。因此，说明了拟议系统的可用性。少
