A Q-enhanced 8th order CMOS active bandpass filter is presented employing a novel two-stage self-calibration technique. The proposed active filter shows the better out-band attenuation performance than other reported CMOS active bandpass filters. The proposed calibration method enables the stable filtering operation affected by neither the input power variation nor the strong interference power...

This paper shows the method of improving the power quality using shunt active power filter. The proposed topic comprises of PI controller, filter hysteresis current control loop, dc link capacitor. The switching signal generation for filter is from hysteresis current controller techniques. With the all these element shunt active power filter reduce the total harmonic distortion. This paper repr...

Chapter 3 presents ANN based adaptive shunt passive filter, whose performance is found to be superior to fixed element shunt passive filter in harmonic and reactive compensation. However, the drawback is that it can provide only partial harmonic and reactive power compensation. Hence, an ANN based digital controller for active filter is developed. It compensates for the major portion of source ...

Obtain at least three different magnitude approximations that satisfy the following specifications: Figure 1 Four different approximations (Butterworth, Chebyshev, Elliptic and Inverse Chebyshev) were obtained for the given specifications using the CAD software FIESTA2. First, the transfer function and main performance plots will be shown for each of the approximations and then, a comparison be...

Nowadays, LCL filters utilization to suppress the grid-connected inverter switching harmonics is expanding and various methods such as capacitor current active damping scheme could be investigated to damp out these harmonics. However, the computational delays including control system, and PWM switching delays have significant effect on damping system stability. In most of LCL filter parameter d...
