<P>PROBLEM TO BE SOLVED: To provide an inverter device capable of appropriately detecting connection failure of a current detector. <P>SOLUTION: A resistance 28 is connected in series between a positive-side terminal (power source supply terminal) of the current detector 15 and a DC power source, and a power source current of the current detector 15 flowing via the resistance 28 is monitored by a disconnection detector 29. When the disconnection detector 29 detects that the power source current is zero, it is determined that the connection failure occurs between the current detector 15 and a control circuit 20. By disconnecting a PWM controller 23 from an inverter circuit 13 by an inverter forced off circuit 27, output of the inverter device 1 is forcedly turned off. <P>COPYRIGHT: (C)2012,JPO&INPIT |
