Abstract :
A new description of the three-phase four-switch converter aimed at compensating reactive power in the general case of unbalanced source voltages is proposed. A mixed p-z approach based on integral transformations (the Laplace and modified Z-transform) is suggested for obtaining solution in a closed form. The analytical procedure is verified by experimental results to confirm the effectiveness of the proposed control scheme.
