ータ装置。DC power is supplied to the inverter device via a chopper device for DC voltage adjustment, and the inverter device converts it into AC power, while the output voltage of the inverter device is detected by a voltage detection means, and the detected voltage and voltage setting are The DC voltage applied to the inverter device is controlled by applying the deviation from the set voltage set by the means to the voltage regulator and controlling the conduction rate of the chopper device according to the output of the voltage regulator. In a chopper-controlled inverter device that maintains the output voltage at a set value, a voltage in an intermediate circuit between the chopper device and the inverter device is detected, and this detected voltage is negatively fed back to the voltage regulator via a differentiating circuit. do,
1. A chopper control inverter device, characterized in that a sudden change in the output voltage of an inverter device is prevented by controlling the current flow rate of the chopper device according to a change in voltage of an intermediate circuit.
