Title:
CONTROL APPARATUS AND CONTROL METHOD FOR AN AC ROTARY MACHINE
Document Type and Number:
WIPO Patent Application WO/2012/011155
Kind Code:
A1
Abstract:
The disclosed control apparatus (1) for an AC rotary machine comprises a control circuit (2), an electric-power converter (3), a current detector (5), and a voltage detector (7). The control circuit (2) is provided with: a start-up current command device (18) that generates a start-up current command; and a start-phase setting device (20) that sets an initial rotational phase, which is used in a start-up control process, on the basis of the direction the AC rotary machine (4) is rotating immediately after start-up and the polarity of a current detected by the current detector (5). This configuration reduces the current amplitude and torque shock immediately after starting the start-up control process, allowing the AC rotary machine to be reliably and stably restarted without the use of a protective operation.
