Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/125637
Kind Code:
A1
Abstract:
Disclosed is a power conversion device comprised of a power converter (2) which converts DC voltage to AC voltage and applies the voltage to an AC rotator (1), and a controller (60) which controls the power converter (2) based on operating commands (PB) from the outside. The device is also comprised of: a first computation unit (9) which calculates and outputs first voltage command values Vd*1, Vq*1 for the power converter (2), and the magnetic flux jds, jdr and the angular frequency w1 of AC rotator (1) from the current command values id*1, iq*1 based on the d-axis current detected value (id) and the q-axis current detected value (iq) detected by the AC rotator (1), and the operating command (PB); and a second computation unit (10) which sets at least one of the magnetic flux jds, jdr and the angular frequency w1 input from the first computation unit (9) as an initial value, and calculates and outputs second voltage command values Vd*2, Vq*2 and the angular frequency w2 for the power converter (2).
