Abstract:
A converter apparatus includes: a converter for converting an AC voltage into a DC voltage; a DC link capacitor connected to the converter; a voltage detector for DC link voltage; a charging circuit for the DC link capacitor; a charging circuit controller for a switch connected with a charging resistor; a current detector for detecting a current of the converter; a turn-on controller for controlling the turning-on of power devices; a switch for connecting or disconnecting a power supply; a power supply monitor for monitoring a connection state of the power supply; a threshold value setter for setting a first or second threshold value; and a failure detector for determining the presence or absence of the failure of the power devices by a comparison between a current flowing upon turning on the power device, immediately after disconnection of the power supply, and the first or second threshold value.

Claim (Index 7):
The method for detecting a failure of the power device according to  claim 6 , wherein when the power device is turned on, a charging circuit disposed between the converter and the DC link capacitor, for charging the DC link capacitor, is controlled so that an excessive current does not flow through the power device.
