Active damping of grid-connected LCL filter resonance by means of an observer loop to estimate the capacitor current is a well-known method. However, with variation of the grid side inductance due to grid conditions, the system robustness has to be checked. This work discusses the effect of the observer design on the system robustness against grid side inductance variation. Different values of resonant...
LCL filters are widely used for grid-connected converters because its superiority over L and LC filters, however the resonance problem produced by these filters requires a more effort in the design process to damp it. Active damping techniques which use the sensed capacitor current are widely used in this regard to solve this problem; however this requires an increase in the number of sensors. Based...
PWM converters are widely used to connect the distributed energy sources to the grid. LCL filters are widely used for these converters because its superiority over L and LC filters, however the resonance problem produced by these filters requires a more effort in the design process to damp it. Active damping techniques which use the sensed capacitor current are widely used in this regard to solve...
In this paper, A two-phase interleaved boost converter (IBC), which is based on Adaptive Neuro-Fuzzy Inference System (ANFIS) for photovoltaic (PV) system is proposed. The proposed system has two inputs and 1 output. Two inputs of the proposed system consist of solar irradiation and temperature. Meanwhile, the output of the proposed system is aduty cycle. The duty cycle is used to generate Pulsed...
