Description: In higher power applications to utilize the full line power and reduce line current harmonics PFC
Pre-regulators are generally required. In these high power applications interleaving PFC stages can
reduce inductor volume and reduce input and output capacitor ripple current. This results in smaller overall
magnetic volume and filter capacitor volume increasing the converters overall power density. This is made
possible through distributing the power over two interleaved boost converters and the inductor ripple
current cancellation that occurs with interleaving, reference [5]. This application note will review the design
of a 300W two-phase interleaved power factor corrected (PFC) pre-regulator. T Platform: |

Description: PECTRUM of the input current drawn by the electric
drive from the network is affected by the used type of the
input rectifier. In the case of the diode rectifier, the number of
its pulses is decisive. Standard AC adjustable speed drives
utilize the input three phase six-pulse diode rectifier for the
AC-DC conversion. These drives generate harmonics into the
network, so the drawn current is not harmonic, but nonharmonic
with a high level of distortion if no harmonic filter
is used. The input current total harmonic distortion is
calculated from the formula Platform: |

Description: In this paper, an efficient active power filter (APF) scheme is developed to estimate and compensate for harmonic distortion in an electrical power network. The developed APF control scheme is based on a double proportional feedback controller and a single-phase voltage-source half-wave bridge inverter. The proposed filter uses a Multi-layer Artificial Neural Network (MLANN) with a shift method for estimating system harmonic currents and voltages at a dedicated point. The proposed scheme is tested on a 13 bus industrial distribution system. The obtained results ensure the effectiveness of the proposed filter. The system is simulated in MATLAB-Simulink and simulation results prove that the polluting harmonics have been greatly reduced. Platform: |
