Abstract
A power converter apparatus converts electricity supplied from a power source into a different form and outputs the electricity to an output line. The apparatus includes a ground-fault detector and a simulated ground fault generator. When the ground fault detecting signal is output within an predetermined time and the output of the ground fault detecting signal is stopped as the simulated ground fault generator stops operating, a control section causes the power section to continue outputting electricity. When the signal is not output within the predetermined time or when the output of the signal is not stopped as the generator stops operating, the control section stops the power section. Therefore, the apparatus detects abnormality in the ground fault detector and continues supplying electricity without interruption when the detector is in a normal state.
