LCL Filter Design for Grid-connected NPC Inverters
... frequencies; for example in overhead lines. Nevertheless, in grids with noticeable underground cable share, the grid impedance under higher frequencies (over 2000 Hz) is generally smaller in such a way that high frequency components can be neglected. A requirement for such a procedure is the calcula ...

Synthesis of Voltage-Mode All-pass Filter Employing Single Current
... response, however, changes from 0° to 180° for a one-pole filter over the desired frequency range. All-pass filters are used in circuit design to perform various frequencydependent time-alignment or time-displacement functions and they play essential role in audio systems [1]. Other types of active ...

... greatly attenuated by the inner filter stages. PWM motor drives, however, typically switch at very low frequencies (10 kHz in the example considered here), which are well below the frequency range covered by EMI specifications. Therefore, a significant amount of the fundamental ripple appears at the ...
