Abstract


In this paper, three grid-side filter topologies for grid-connected three-phase photovoltaic current-source inverters are designed and assessed based on the Total Harmonic Distortion (THD) of the grid currents, on the power factor in the connection to the grid, and on the filter losses. A second-order CL filter with passive damping resistors in parallel with the filter inductors is first sized and evaluated. It is then improved by removing the resistors and using active damping, with the virtual resistor method and feedback of the inductor voltages requiring no additional measurements. The analysis is conducted taking into account the delays introduced in the control circuit and the cross-terms in the state-space equations in the synchronous dq frame. A fourth-order CLCL filter is also sized and considered as an alternative grid-side filter topology to reduce the switching harmonics. Simulation and experimental results obtained with a direct control approach confirm the proper sizing and operation of the filters. Based on the THD of the grid currents and filter losses, the second-order filter with active damping presents the best results with a THD lower than 5 % and nearly negligible losses.
