Abstract: The present invention provides a load impedance estimation and repetitive control method capable of allowing inductance variation for an inverter, wherein the method is applied for predicting corresponding next-period switching duty cycles for four switching member sets of the inverter by way of sampling three phase voltages and calculating next-period voltage compensations based on the previous line-period voltage compensations. Moreover, during the calculation and prediction, the method also involves the inductance variations of the output inductors of the inverter into the load impedance estimation matrix equation. Therefore, the three phases four wires inverter with the presented load impedance estimation and repetitive control method can provide a steady output voltage to the loads even if the originally-connected loads are replaced with other different loads.
