Claim 3:
4. The power conversion device according to claim 3, wherein
the power conversion circuit includes:
a rectifier circuit having an input end connected to the power input terminal and an output end, to convert an AC voltage of input AC power into a DC voltage of DC power and to output the DC voltage of the DC power to the output end; and

an inverter circuit having an input end connected to the output end of the rectifier circuit and an output end, to convert the DC power into AC power of an AC voltage on a basis of the input DC voltage and to output the AC power to the output end, the output end being connected to the power output terminal, and
the determination circuitry includes:
current detection circuitry to detect a current flowing through a ground line connected to the shield terminal; and
comparison circuitry to compare the current detected by the current detection circuitry with a set value and to output disconnection detection information for disconnection of the shield of the signal transmission cable on a basis of the comparison result.
