In addition, the same reference numerals in the drawings indicate the same or equivalent parts. Amendment November 26, 1980 The scope of claims for utility model registration is amended as follows. O Utility Model Registration Scope of Claim A converter unit that converts AC input power into DC; an inverter unit that inputs the output through a smoothing capacitor, converts the output into variable voltage and variable frequency, and supplies it to the AC motor; In an inverter device equipped with a regenerative brake control circuit that detects when υ exceeds a predetermined value and causes the regenerative brake resistance to consume the stored energy, the regenerative brake resistance is used as the discharge resistance of the smoothing capacitor. An inverter device which also has a discharge circuit which uses the capacitor voltage as a driving source, detects whether the input power source is turned on or off, and discharges the capacitor voltage to the regenerative brake resistor when the input power source is turned off. −
