Title:
交流回転機の制御装置および制御方法
Document Type and Number:
Japanese Patent JP5190155
Kind Code:
B2
Abstract:
A control apparatus (1) for an AC rotary machine includes a control circuit (2), a power converter (3), a current detector (5), and a voltage detector (7). The control circuit (2) has: an activation current instruction unit (18) which generates a current instruction for activation; and a start phase setting unit (20) which sets an initial rotation phase for activation control, based on the rotation direction of the AC rotary machine (4) just after activation and on the polarity of current detected by the current detector (5) just after activation. Thus, the current amplitude and torque shock just after activation control has been started can be reduced, and assured and stable reactivation is allowed without causing the protection operation.
