Abrégé
An imbalance failure detection circuit according to an aspect of the present invention is for detecting an imbalance failure of electronic device apparatuses each including electronic devices and including a plurality of current paths connected in parallel, the imbalance failure detection circuit being provided with: a detection unit that has a plurality of coils arranged so as to surround the current paths and connected in series, and that outputs a coil sum voltage which is the sum of induction voltages of the coils generated by current flowing through the current paths; and a control unit that detects imbalance failure of the electronic device apparatus when the coil sum voltage from the detection unit exceeds a prescribed value range.Classes IPC ?
