Abstract
Provided are a detection method for an inverter system, an inverter system, and an arc detection system, which belongs to the field of inverter systems. The detection method for an inverter system includes: obtaining a first actual value of a sampled signal obtained through sampling for the inverter system by an arc detection system, where the sampled signal is an input electrical signal or an inductive electrical signal of the inverter system; determining a saturation state of the sampled signal based on at least one of the first actual value, a maximum amplitude corresponding to the sampled signal, and a minimum amplitude corresponding to the sampled signal, where the saturation state includes saturated or unsaturated; and performing arc detection based on the saturation state.
