Title:
CURRENT SOURCE INVERTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/104008
Kind Code:
A1
Abstract:
Disclosed is a current source inverter device which controls the power factor in an arbitrarily configurable manner without a magnetic pole position detector. The device is provided with a current source inverter; a motor supplied with alternating current power from the current source inverter; and a control means which detects the terminal voltage of the motor, calculates the motor's internal induced voltage and the motor current that flows in the motor based on the detected terminal voltage, and controls the current source inverter. The control means calculates the phase difference (θc) between the terminal voltage and the motor current, the phase difference (θx) between the motor current and the internal induced voltage, and the phase difference (θv) between the terminal voltage and the internal induced voltage. An adjustment angle (θα), which is the error in the phase difference between the motor current and the internal induced voltage when the set value of the phase difference (θx) is θy, is obtained from the conditional equation θα = θv - θy - θc.
