Abstract
(EN)
An inverter device (1-1), provided with: an inverter circuit (3) for converting a DC voltage into an AC voltage; a phase current detection unit (5) for detecting the phase current of the inverter circuit (3); and an inverter control unit (4) for estimating the DC voltage on the basis of the difference between the phase current detected during operation of the inverter circuit (3) and a predefined reference value for the phase current, and controlling the inverter circuit (3) on the basis of an estimated value for the DC voltage.
