  • Abstract:
  • Power electronic devices like cascaded multilevel inverter were developed to produce the required voltage and current waveform from many levels of DC voltages. Therefore, these inverters are striking topologies for their implementation in shunt active power filter to be used in medium and high-power application. So, this paper displays a five-level cascaded multilevel inverter working in a shunt active filter to eradicate current harmonics generated by different non-linear loads and compensates the reactive power. The system also includes PI controller for voltage regulation in SAPF in its DC side and for generating inverter switching pulses, triangular carrier current controller is worn. The control strategy used for production of reference compensation currents is unit impulse theory. So, main emphasis is on extenuation of harmonics from nonlinear loads with the support of PI controller for DC voltage regulation.
