とする回生電力吸収回路。 A configuration in which a series circuit of a resistor for absorbing regenerative power and a switching element is connected between the DC power lines of the inverter device, and the switching element is made conductive when the voltage between the DC power lines exceeds a set value. The first detection means outputs a first detection signal when the voltage between the DC power supply lines is equal to or less than the set value, and the switching element is configured to determine the conduction state of the switching element based on the voltage across the switching element. and a signal generating means that generates an abnormal signal when both the first and second detection signals are output. A regenerative power absorption circuit featuring:
