Claim 6:
7. The motor drive device according to claim 4, comprising:
a first voltage detector for detecting the first voltage;
a second voltage detector for detecting the second voltage, the second voltage being the voltage on the direct current side of the converter circuit; and
a control unit for controlling the converter circuit on the basis of a detected value of the first voltage, a detected value of the second voltage, and the detected value of the first current, wherein
in the case in which the determination result of either the first overcurrent determination unit or the second overcurrent determination unit indicates an overcurrent, the control unit stops generating control signals for controlling the first switching elements, and stops generating control signals for controlling the second switching elements.
