Title:
ALTERNATING CURRENT ROTATING ELECTRICAL MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/105106
Kind Code:
A1
Abstract:
The objective of the present invention is to provide, using a simple circuit configuration, an alternating current rotating electrical machine control device capable of accurately compensating for errors in a real on-duty with respect to a command on-duty calculated from a command voltage. On the basis of a detected value of an midpoint potential, which is the potential of a connecting point of a serial connection in a series circuit, a control device (1) of an alternating current rotating electrical machine detects a real on-duty (Dr) of a switching element, calculates an on-duty error (ΔDer) from a difference between a command on-duty (Do) and the real on-duty (Dr), and corrects a voltage command or the command on-duty (Do) on the basis of the on-duty error (ΔDer).
