Title:
INVERTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/146437
Kind Code:
A9
Abstract:
Provided is an inverter device which exhibits excellent tracking performance in the event of load variation. The inverter device is provided with: an inverter circuit (20); d, q/u, v, and w conversion units (50); a line voltage effective value calculation unit (53); a modulation voltage conversion unit (55) which converts a line voltage effective value obtained by the line voltage effective value calculation unit (53) into a modulation voltage for each control period; and a comparator (52) which compares signals having waveforms corresponding to voltage command values for the u, v, and w phases with the modulation voltage at control periods, and outputs a pulse pattern for an upper-arm switching element and a pulse pattern for a lower-arm switching element of the inverter circuit (20).
