This paper investigates the performance of a grid-connected current-source converter topology for PV cells. The constant current source is realised by a large DC link inductor connected in series with the PV panel. A boost switch (named as current waveshaper) is used to produce a modulated output current that resembles the rectified grid voltage, which is in-phase with the grid. An H-bridge inverter with line-frequency commutated thyristors “unfolds” the output of the current waveshaper to produce a sinusoidal AC output current. The proposed converter concept is verified with simulations and preliminary experimental results.
