INVERTER SYSTEM
First Claim
1. An electronic device including an inverter, comprising:
- an anomaly detection circuit that detects anomaly caused by disconnection discharge in circuit wiring of said inverter or proximity discharge between high and low voltage parts of said circuit wiring; and
a control part that stops an operation of said inverter when said anomaly detection circuit detects the anomaly.

Abstract
An inverter system which converts DC input into AC output and supplies the AC output to a load such as an FL tube detects change in a circuit current due to anomaly such as discharge without contacting with a current route. Relating to an inverter which converts DC input into AC output and supplies the AC output to a load, change in a circuit current of the inverter is detected through the medium of magnetic flux change due to the change in the circuit current caused by discharge. For example, if change in a current occurs in the circuit current of the inverter by disconnection discharge or ground-fault discharge occurring in a current route including a load of the inverter, magnetic flux change occurs in circuit wiring and a space of a core gap of a transformer of the inverter. The change in the circuit current is detected through the medium of the magnetic flux change without contacting with the circuit wiring or the transformer.
