Description: 本例介绍直接合成带阻滤波器的方法，n阶滤波器能实现n个传输零点-A direct synthesis technique of a new class of bandstop
coupled resonator elliptic filters is presented. Two different
coupling schemes, which both include source–load coupling are
used. The first coupling and routing scheme is the standard folded
structure used in implementing bandpass elliptic filters with
transmission zeros using resonators. Platform: |

Description: This paper presents the modeling and implementation of a three-phase DSTATCOM (Distribution Static
Compensator) using STF (Self Tuning Filter) based IRPT (Instantaneous Reactive Power Theory) control
algorithm for power quality improvement. It is used for harmonics elimination, load balancing and
reactive power compensation at distorted PCC (Point of Common Coupling) voltages under nonlinear
loads. An adaptive fuzzy logic controller is used to control the dc bus voltage of VSC (Voltage Source
Converter) based DSTATCOM to improve the response and to reduce the overshoot and undershoot of

Description: The circuit models a standard shunt AHF with IGBT inverter and series inductor on the AC side and DC capacitor energization. The load consists of two diode rectifiers which are phase-shifted by 30 degrees. The Delta-Y connected rectifier is connected after 10 cycles to change the load 6-pulse to 12-pulse.
The AHF uses a PLL to generate a reference sinusoidal source current which is in-phase and has the same RMS gain as the load current. The current error between the load current and the reference current is generated by the IGBT Bridge through hysteresis switching. The AHF aims to inject this current error at the point of common coupling in order to match the source current as closely as possible with the reference current.-The circuit models a standard shunt AHF with IGBT inverter and series inductor on the AC side and DC capacitor energization.
