Abstract

This paper proposes a novel on-line inductance identification method to account for inductance saturation in current controller design for single-phase grid-connected inverter with single inductor filter. The predictive control method with delay compensation is used which has wide bandwidth and reaches steady state within one switching period in current control loop. A multiple-sampling method is developed for instantaneous current feedback, which can get average current even in DCM operation and low duty ratio conditions. An on-line inductance identification technique is proposed to compensate the model inductance parameter variation and stabilize the transient disturbances. Simulation and experiment results have been carried out to verify the results.
