Capacitor failure detection

摘要

The inventive technique includes methods, devices and computer-readable media for monitoring a magnetic device. One such device includes a magnetic core for generating a magnetic field, a power supply and a capacitor bank that is charged by the power supply and is for pulsing the magnetic core. The device also includes a processor that measures a charging response of the capacitor bank during charging and determines whether the measured charging response is within a predetermined tolerance of a predetermined charging response.
