Abstract
A detecting method for detecting an output impedance angle of an inverter includes controlling an inverter to output a second voltage signal and a current signal based on a first voltage signal; calculating an active power and reactive power based on the second voltage signal and the current signal; and calculating an output impedance angle of the inverter based on the product of the active power and a first amplitude parameter, the product of the active power and a second amplitude parameter, the product of the reactive power and the first amplitude parameter, and the product of the reactive power and the second amplitude parameter. The first amplitude parameter corresponds to a first amplitude of the first voltage signal, and the second amplitude parameter corresponds to the first amplitude of the first voltage signal and a second amplitude of an AC voltage.
