Design and control of a three-phase active rectifier under non-ideal operating conditions

Industrial engineers face many nonideal operating conditions in the design of the active rectifiers: too long computation time, presence of acquisition filters, AC phases unbalance, location of the grid voltage sensors after a dominant reactance and passive damping if an LCL-filter is used. The phenomena generated by these conditions are generally nonlinear. Hence the first step is to find out how much each of them affects the system's overall performance. Then new rules for the tuning of the controllers can be developed on the basis of the analysis of the transient behavior and of the steady state harmonic content of the DC voltage and of the AC current. This procedure is developed in this paper through simulations and laboratory tests.
