Abstract: A ripple current that flows into a main-circuit capacitor is estimated based on a system impedance and output power to a motor, thereby making it possible to always perform ripple-current estimation and life estimation computation for the main-circuit capacitor online. Because data of the system impedance which largely affects the ripple-current estimation for the main-circuit capacitor is used, the capacitor ripple current can be estimated according to the magnitude of the system impedance. This enables highly-accurate life estimation computation of the main-circuit capacitor.
